Seriously every time I want to update my arduino skills I find that the bloke that seems to have something of an Indian dialect always delivers in a fast decisive manner and it's always clearly layed out with no fluff. You Sir are a Gentleman and a scholar. Another success. Thank you so much brother. Greatly appreciated. Subbed!
Thank you very much. I am Canadian, Persian from Afghanistan.
Your more than welcome Sir, my apologies for getting the heritage completely wrong . Your sage knowledge allowed me to couple the relay to a Geeetech voice recognition module. It's just a beginning phase but now I can voice activate my a bed lamp :).
Robojax you sound more like arab to me, hehe 🤣
Hi I from India could you tell me about the scope of this aurdino in electronics engineering sector
@@robojax You're just Canadian now. We told you our secret handshake.
as soon as you started to talk I just knew you were Canadian. clear and to the point. no wasted talking.

Great video explaining the Songle relays. I just included them to control my train turnouts and isolation (power) tracks using an Arduino. Since the turnouts only need about 150ms of power to trigger the solenoid, these are perfect! Great job!!

You are very welcome. I am glad you found it useful.
I couldn’t figure out why mine wasn’t working and now that you explained it I’m super happy, I liked your video!!
Glad I could help!
what was the problem?
Ahmad, you design and build some of the most useful circuits available. Excellent channel!!
Thank you, I used this exact method to upgrade my laser cutter to automatically activate my air assist pump during a cut when activated in the cutting software so much cheaper to build a relay control box than spend £260 on a kit for the same thing!
Thank you so much for your great videos. I already bought many relay to do the same. I can't do it for long time. Now I follow your teaching and to get success. Wish you good luck sir.

Great video, love from Zimbabwe.
Thanks you for Canada.
Thank you for posting this. I would love to see a follow up video with the Arduino controlling a relay based on input to the Arduino. In other words if I press one button the relay would be activated for one second. If I press a second button the relay would be activated for 10 seconds and if I press a third button the relay would stay activated unless a separate signal told Relay to shut off.
I am trying to control an AC motor that will raise a platform to various heights.
Thank you Mr Robojax! You are always so clear in yoir explanations.. You don't rush your tutorials..
You are welcome. I am glad you found it useful. Ahmad from Canada.
Good explanation without a drip feed, fluff, obfuscation or ego tripping! 😀👍
Me again, thanks to your awesome explanation, I build this! Kudos!
thanks this is really great especially for beginners like me...i have question can i use the arduino only for power supply purpose and control the RF relay using an RF transmitter remote controller?
you are welcome. Relay is a SWITCH which you can turn ON/OFF something. Yes it only connects the and disconnects. so it is up to you where you want to use it for that purpose.

Simple and concise explanation, best I've seen
What is the minimum voltage requirement for the S pin of relay
Can we connect the S pin with 3.3v or less
The operating voltage is 5V for this relay but you can get the same relay at 3.3V
@@robojax how can I contact you bro
Am developing an electronic project for my college and i need relay to complete that Project but i have a lot of doubt related to it.
plz give me your contact info so that I can discuss all doubts briefly with you
Thank you ❤️❤️
Yes you can. Use a boost converter to convert 3.3V into to 5V. Search my channel for boost
is there a way to stop the relay pulsing on on power up? As in the video my relay briefly pulses on when power applied. I want to use my relay to send signal to open a gate but if everytime there is a power interruption the gate would open on power up not really ideal.
Do we still need a relay if our power source for the arduino is a 12v Battery (Like for motorcycles) and light up a bulb from a 12v Battery power source also?
If you watch the video, you will know the relay is a switch. If you need to turn light ON or OFF in a certain way like turn on for 3 sec and off for 8 sec then you need Arduino and the relay (or there is a programmable relay module). If that is not the case then use normal switch.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??
Thank you! Total beginner here and this was very clear on the how, what and why.
I'm hoping you can help me with a question: I want to build a circuit like this, but I want to use a limit switch to turn the light on and it stay on until I push a button to reset it. I guess the best way to explain it is like an alarm. When the circuit is open the light goes on, but stays on until I reset the circuit with a button. How can I work that into this?
You are welcome. did you search for "push ON" in my channel? Here the video: th-cam.com/video/7CCSRs5bvH0/w-d-xo.html
Hi, thanks for your work!. This seems to be the way I want to work with a washing machine motor, BUT; I need the ON signal to be for one second, then off 2 seconds, then on again 1 second, alternating between 2 different pins. I suppose this is possible but I wanted to check for feedback before I go and burn things. Any help appreciated!

Very helpful, thanks for the video!
Awesome video tutorial. I’m a beginner. Just wanna ask if I follow your tutorial to control an AC bulb, what should i use: a High Level Trigger relay, or a Low Level Trigger relay?
Thanks. that doesn't matter which one you use. The relay shown in video is HIGH trigger.
Hi Robojax -- do you have any advice for how to set triggers for the relay to turn on? I'd like to use a keystroke with AutoHotKey to turn my relay on and off (maybe it executes a Powershell script or similar?), but I am having a hard time finding a tutorial for something like this.
Hi, here Control relay and AC bulb from Windows Shell Command line via USB and Arduino
th-cam.com/video/HzLCkzX5q3w/w-d-xo.html
Great video! Thank you very much
Helli, I'm new on this field. I have a question, why you need to connect both the signal pin and the + pin ?
On the control side of the relay there are only 2 pins, one of which is GND
Hi, it seems you have not watched the video fully. Please watch.
please answer asap, how can i long the light on ? your videoa are very nice and helpful
Hi, what do you mean by "how can i long the light on" do you mean "How can I change the time the light is ON?" if so, then just add delay(2000); after the line where the light is ON. this will keep it on for 2 seconds. for 10 seconds make it 10000 (millisecond) and so on. the same way you can do it with OFF.
The project is very good but i want this relay and ardunio to control water heater can i on and off heater between two temperature limits?
yes you can. You would have to use a temperature sensors like DHT11, BMP280 or something like that. I have video for both. Search my channel.
hi mate sorry for asking this you should of use Bootlace ferrule, not solder, solder well melt.
Hi, this is the first time I am hearing the " Bootlace ferrule,". I just did search for it but still didn't get it. is it a crimp device or some kind of glue?
Thanks for clear explanation! Can I use it with DC setups as well? Thanks again!
You are welcome. yes. See the title and also I mentioned in the video "AC or DC load" . Because AC is the hardest, I demonstrated and the same is true for DC.

I really appreciate these videos.
Very useful, but it is possible to have the bulb turned on for larger periods of time (like 15 minutes or so)?
thank you. yes. It can be turn on for unlimited time. for example for 25 minuets, 25x60=1230 seconds and because we use milliseconds, add 000 and becomes 1230000 and type delay(123000);

Thanks for that! One qustion though, for some reason it works the other way around - the relay is activated (circuit is closed) for 5000ms and open for 3000ms. What could be the problem? Thanks again!
You are welcome.
This is very normal. There are two types of relays. Your relay is LOW level trigger. Meaning it is activated with LOW and goes OFF with HIGH. For this reason the code looks the opposite of what you expect.

Thanks! I was wondering how to connect a relay to a solenoid valve for pneumatics!
Hello, I wanna ask something... I wanna connect the relay to plug 3 pin, theres earth, live & neutral wires. So which wires do i need to cut & connect it to the relay ?
earth is for safety. You should cut live. But neutral will also work. Live is somewhat safer.
Please be careful. In AC Earth means something different. In DC earth is really what neutral is in AC. When transferring AC to DC you ignore the AC Earth.

Very nice and helpful videos.. Finally found a channel to learn arduino in a very easy way.. Thanks man..
You are welcome. I am glad you found it useful.
Hi Robojax, nice video thank you!
Does it matter whether the relay is inserted in the "live" or the "neutral" side of the mains AC supply? I can't help thinking the appliance would be permanently "live" if the relay were inserted in the neutral side. Thanks!
In many countries, the live and neutral wires are not distinguished when plugging in the device. If you can distinguish it, connect neutral for safety purpose.
But in terms of operations, it doesn't make any difference.
Robojax...thanks for this great video and source for all the projects. Really appreciated. You might want to check with an electrician / electrical engineer on the statement that "In many countries, the live and neutral wires are not distinguished when plugging in the device. If you can distinguish it, connect neutral for safety purpose. ". It's not 100% false, yet not accurate either. And the difference between the two can harm people. I suggest you read the book of Karl Riley (Tracing EMF's).

Hello. Thank you very much. It is very helpful. I am working with a project of pneumatics cylinder. In need to actuate a 220 V AC solenoid valve with the help of Arduino and relay. So to actuate the solenoid valve is the connection will be same? Can i treat the solenoid valve as the light.
Hello, you are welcome. Here is my video on DC actuator th-cam.com/video/EaoB6lfnS7g/w-d-xo.html but I am not sure about AC actuator and types.
Hi sir! Can I use HCW-M421 Timer module instead of the relay you used in your video?
Hi, no you can't. you need a simple rely module .
A very clear explanation, thanks.
Glad it was helpful!
You have not said about the power adaptor jack in left corner below usb jack. Why it is not linked and explain. Why left unattended.
Hello, this video is about Relay. That jack is explained when the Arduino board is explained. You can connect up to 12V at the jack. here is the jack wiring i1.wp.com/www.open-electronics.org/wp-content/uploads/2015/07/Fig9.png
Hi Robojax, will the relay get warm at all when we use it to control a 10W LED? And if you have time please do a tutorial or review on the HLK-PM01 power supply. Thanks.
I just check the specs. It is AC to DC converter and maximum current it can handle is 3W at 5V. So you are over loading it by the factor of 3. See photo if this is the right product. ae01.alicdn.com/kf/HTB1W2uJOXXXXXayXpXXq6xXFXXXO/220173842/HTB1W2uJOXXXXXayXpXXq6xXFXXXO.jpg
So you have to reduce the load to 3W or lower.
Thanks for the suggestion. I will look into it.
Thanks Robojax.
which wire from the bulb is connected to the relay and how did you find positive and negative?
Please watch again. There is no positive and negative in AC. We have neutral wire and Live wire. In Canada 🇨🇦 we know the live wire and it is fixed on the wall.
Thanks bud! This was succinct
thanks for the helpful tutorial!
Hello Sir, I plan to use this relay to connect from 5V arduino to 12V DC Pump (4-7A). It is written that the DC adaptor to power the pump is 12V 10A. is it a robust solution to use this relay in a closed enclosure in the farm? or should I upgrade the relay spec? Thank You Very much Sir !
I want to run pneumatic solenoid (24 Volt DC) using Arduino....do I need a 24 volt battery for it or just a 9Volt small battery connection to the Arduino is enough?
Arduino needs it is own power so 9V will work for it. For your solenoid, you need separate power. In this case instead of bulb use your solenoid and instead of AC use your 24V.
Hi Robojax, as a beginner and really concerned of safety. I would like to ask, does it matter whether you use the negative or positive side of the lamp wires? thanks in advance.
Once AC is connected the relay should not be touched. when you connect AC lamp wire. We have no + or - but we have Live and Neutral. In some countries and some plugs you can connect the plug to the wall in any ways you like, so you will not know which once is live and which one is neutral. It will make it much safer if you connect the neutral wire. But when the light is OFF, there is still possibility of harm unless the plug is disconnected.

Thanks for your videos very interesting
does the relay power the arduino, or does the arduino need to be connected to a USB cable while the circuit is being used?
Arduino board has multiple way to power it up. USB is one of them which powers up and upload the code to it. Relay module can be powered from any 5V source. we are using Arduino board to power it up. Arduino Step by Step course that starts here th-cam.com/video/-6qSrDUA5a8/w-d-xo.html good luck
Hi
I need a relay unit that can tigger on and off of a plasma cutting machine following a design from a computer system which the input is 5volts.
Thanks and looking forward to hear from you.
Regards
Hi, this is just a swtich. only you have to read the realy current rating which says "10A" and your laod or plasma cutting machine also should not exceed what is written on the relay.
Can this be used to power Arduino Nano? I plan to put my project near electrical outlet but not sure how to get electricity from 220v to 5v
please watch this video th-cam.com/video/-JD3E7e0RAE/w-d-xo.html
can I use this relay in a 220V line, like in the service drop before the kwh meter?
Relay is a switch . Most relays are rated at 10A. If you are connect it to turn On/off a load not more than 10A then yea you can use it. Read the rating of the relay and use it.
Thank you for the information. Im an aspiring learner about arduino sir and i want to ask this question: Can i also connect a temperature sensor to this system to record the heat released of the ac bulb? The context of my idea is to create an automatic temperature control system where the light bulb turns on/off depending on the status/temperature recorded by the sensor.
Once again thank you for this awesome video!
Yes you can. Search my channel for the word temperature. Here is how to find Specific TH-cam Video in a channel bit.ly/findTH-camVideo

thanks sir very much . i have a question , how can we avoid noise that affect arduino ? when i connect 220 v supply it makes noise to the board and the code is malfunctioned and when i disconnect the 220 v supply it returns to its normal state ?
It should not affect the board. There is not AC connection with Arduino. But you can put 100uF to 1000uF 5v capacitor at 5v terminal and it should fix it.
For 2 lump be sure necessary will use 2x “5v Single Chanel Relay” or there’re other scheme?
Thanks for recording nice quide
If you want to turn both ON and OFF at the same time, then ONE relay will do it. Just connect both both wires to the same relay.

SOS Do I need to solder the wire before putting them in Relay if I have the same type of wire? Thank you!
I mean is it mandatory?
solder makes all treads of wires into one so you can insert them easily. It is not needed.
thank you so much.Simple and easy explanation. Can you post a video to connect the relay to a house circuit. eg. Light circuit or plug circuit; And which wire must we interface on. Thank you so much.
You are welcome. Thank you your suggestion. i will try to make such video in the near future.
Thanks. This is real clear for me as beginner
Glad it was helpful!
if i want to start & stop heater due to change of color from Blue to Pink & Pink to Blue. Can it be possible through Arduino & Relay
Yes possible but I don't have any video on color detection yet.
Sir, would I connect ceiling fan on that relay? That is working or damage relay
this is for AC or DC load. ceiling fan IS an AC load. Yes it will work. Perhaps skipped the video asking about "damage". I just watched the video and indeed I have explained it. So watch it without skipping and you will learn.
Very clear and didactic, thanks a lot :)
You are welcome. :-)
Does the switchside need to be connected for me to test the relay? I am currently using a pi and it is not working regardless of what i do
i did not understand "switchside". I have not mentioned such term. we have 3 pins which I have explained and 3 terminals with screw which I have shown how to connect. This code is for Arduino but if you write your own code for raspeberry pi, it should work.
If i use the 5V relay, can I activate the 12V motor?
yes you can. Relay is just a switch. The load can be DC or AC 5V or 220V.
Hello teacher, I would like to ask if there are 5V and 12V relays on the market. What's the difference between them?
hello, the difference the operation voltage. They both work the same way. If you want to use Arduino it is better to use 5V because Arduino operates with 5V.

Hi, welcome. If are new to relay, then this video from my course will help you better as it has full wiring diagram th-cam.com/video/N-xbxtGGoHw/w-d-xo.html for timing we have Real-Time clock (or RTC) module we can use to control something at exact time and date. here is one full video to use RTC th-cam.com/video/gz9xqvRroDY/w-d-xo.html to make either a clock or just use it as Alarm to control a load.

@@robojax thanks. My question was how long a delay can be programmed into the mega 2560.

for the time there is no limit. You might look at this timer program th-cam.com/video/6DGQhQgr7Ak/w-d-xo.html or timer with dispaly th-cam.com/video/BhEIFzFSMuE/w-d-xo.html
Hello. I don’t use arduino but an other output signal, which is 5Vdc. It doesn’t work. May I know the voltage of arduino signal output. So that I can modify my 5v output to match the arduino output voltage as the signal input with another 5v dc to use the relay board. Thank you. Looking forward to your reply.
this is LOW trigger. Turns ON with LOW (0V) and turns OFF with 5V.
Thank you help to make my project work. Great lesson!
You are welcome.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??
Hi, It might be a silly question but can you use relay as ON state by default, means if there is no current applied the circuit is closed but when you apply current the relay is OFF state ? The reason I am asking I want to have 2 power circuits but when I am running one I one to terminate the other and vice versa :)
Hi, there is no silly question. Yes you can. inside the setup() after pinMode(....); in the next line turn it on and it will be ON like this digitalWrite(5, HIGH); this will turn the pin 5 high. or whatever pin you have defined. Good luck.
@@robojax Yeah I just discovered Normally open and closed relay which are 4 pin and apparently there are 5 pin relay that can set up for both :) so I will play with either. Thanks!

is that relay can handle 220 volts AC 1400 watts?? thank you for your reply.
you surprised me by your question and made me watch the video. I have clearly explained the rating of the relay and even calculation of power. if you missed then please watch because I have mentioned numbers and how to calculate it.
@@robojax thank you for your response, i watch it twice sir before i ask question, just to make sure because i dont have money to buy new relay if i explode it. and also im not good at english, hope you understand sir, i really thank you for your response.
using that relay that can handle both ac and dc load, will the arduino handle ac load safely?
this is relay. Perhaps you did not watch it. I mention DC or AC load.
Is there a way to dim the light for example if PIR sensor detects an object then the light will go ON and keep it on for sometime. Now if there is no object for 20 minutes, instead of turning off the light but dim the light instead for like 30 to 50% instead of 100% ON.
Thank you.
Not with the relay. I am preparing AC bulb dimming video which will be posted in the near future God willing.
I'm connecting the light fixture to relay then relay to Arudino Board with PIR Sensor. I know how to turn ON and OFF the AC bulb using PIR sensor but I'm curious on how would you dimming the light instead of turning it OFF. Sorry if I'm not clear
Thank you.
Here are many ways using Triac to do it. Here is one example and it seems the circuit should work: obrazki.elektroda.pl/4402156800_1385532477.jpg

Much appreciated. I got my relay working and I am very happy.

hi .. we should cut the pozitif cable or the neutral cable of the bulb?
both will work but HOT or LIVE wire is better to be used here.
can i use the 3.3v slot for the relay? Because 5 v slot already used by other component
what are other components? Here is how you can make additional 5V for other components th-cam.com/video/Vmrmp7reHOY/w-d-xo.html and leave the main 5V for relay. Relay power must be connected to 5V pin. of course there are 3.3V relay modules like this www.amazon.ca/dp/B07YF7R9G9

what is mq2?

Hello Sir, thank you for your tutorial. However I am new to arduino and I have one question to ask. How to prevent the delay affecting my sensor system. Because the delay of relay effect the measurement reading of my sensor? I am looking forward for your answer. Thank you very much sir.
what delay or sensor? this relay will be activated in about 0.3 Seconds. If you need faster response, then use SSD th-cam.com/users/robojaxTVsearch?query=solid
What voltage is the signal? Can it be 1vdc, can it be a tone? What makes up the signal?
Are you new to Arduino? Then starry my course fro here th-cam.com/play/PLHvJ4bw0xno4Z3FC2W07I4D2UP14bOaT2.html and yes the relay can be turned ON with 1vdC
@robojax how can you trigger this with a physical button can you share the code on uno
Please search for push button, Here is how to find Specific TH-cam Video in a channel bit.ly/findTH-camVideo
@@robojax thank you very much sir
Which part of the wire goes into the common terminal and normally open terminal of the relay ? My scenario is, i want to replace a switch with a relay. The switch have two connections. One is the mains supply and the other is the control wire. Now, which wire goes where on that relay ? I'm a newbie so can someone help me with this please...
how many wires have the switch? if it has 2 wires, then do it exactly as it is shown in video. If not then, post the photo of switch at snag.gy and post the link here so I look at it.
Is it possible to show us microstep TB6600 driver Arduino connection with the drivers by the three motors with endstop buttons with relay to stop and run the drill please showing this in video or photo please ? cnc machine?
I don't have any video or project with CNC. I in the future I might go towards CNC but for now it is not in list.
thanks

Hi, is this a low level trigger or high level trigger relay?
Hi, when you see digitalWrite(8, HIGH); and if this line turns the bulb ON, then it is HIGH trigger. Here is the other relay where Low Level trigger is shown th-cam.com/video/g6k8sPJyif8/w-d-xo.html
unable to toggle on and off when connected to realy from esp8266.
connected esp pin as input pin to relay,
5v dv to VCC of relay.
Ground to Ground.
Light lamp glows, but doesnt toggle?
I have not used esp8266 in this tutorial.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??

Thang Tons I'm a complete beginner so I'm probably getting this wrong - but is the key here when he sets pin 7 as an OUTPUT pin therefore only outputting a signal and not receiving anything (i.e voltage). Please can someone clever step in here and clarify! Thank you
Can you run it on 3v ?
You said it needed 5v but would i really need a voltage regulator to run this?
yes if you relay is 3.3V. I haven't seen 3V, but if you have it, yes you can.
What are you connecting to Arduino in ac side relay is it neutral common
I am not sure what you are asking. Arduino works with 5V which you can connect a battery or power adapter or USB charger. Then for AC, has 2 wires which I have shown to cut one and use relay to connect and disconnect it for you. you can watch this video th-cam.com/video/N-xbxtGGoHw/w-d-xo.html which shows wiring diagram if you want to learn more.
Does it matter In which side ac voltage is put in relay in the two wire hot and neutral
Hi
Realy very nicely explained.
Now I want to control this relay at specific time on and off, with the help of RTC DS3231. But could not find the library for DS3231.
Can you please help with the code.

You will need light dimmer. I will post the video soon. I have already posted for Patreon members.
Question.
If im using a welder, I wanted it to turn on when my Gcode starts my tool path start weld and I want it to turn off when my tool path changes position then I want it to turn back on when i want to make another weld. How would that be coded?
I don't know how do you get the output from your tools that work with Gcode. But it seems very simple. assuming you get output from your tool on a wire that goes HIGH or 5V and LOW or zero Volts. than you can connect it to Arduino for example pin 5
so Here I have written a code for you codeshare.io/GAnNrx please let me know if you were able to make it work
Thanks. I will give that a try and see if it works

Bro how are you embedding the code to automatically run on startup of the unit when powered?
You can set the relay to be OFF or ON at power up. Just put the code inside setup() and it will behave like that if it was OFF or ON.
Good explain sir...sir now how to connect switch mode and relay mode.like(manual mode and automatic relay mode) please explain sir.
did not understand your question.

@@robojax of course, digitalWrite HIGH and LOW close and open the circuit respectively. But, when close, why it's not output 5 v??? Please kindly elaborate. Thanks.
Hello sir, can I use an extension chord to make the connection with the relay instead of the lamp connecting to the relay? Cool video btw 👍🏼
yes. If you safely prepare your wiring yes. Consult an licensed electrician to be safe.
Robojax it should be the same circuit schematic as what you did here except using the hot from the extension chord instead of the lamp..one end of the hot wire should connect to NC and the other to C..is this correct?
