Hi, I built this electronic circuit, I was helped by your guide, everything works great including with a connection to Raspberry Pi, I loved the step by step in your tutorial. It helped me a lot, thank you very much.
I followed your video and schematics and got a module up and running, thanks for that! Now I have a problem when I connect it to a ESP8266, I connect it to GND and 5V, but when I do so the relay clicks and goes into NO, without the IN pin being connected. When I connect the IN pin it goes to NC. This doesn’t happen when I use a 5V connection from my usb charger. What could be wrong?
When using with esp8266 modules, there are some that are not there to be used on the module's pins. gpio14, namely d5b and d6, can drive switching circuits such as relays. If you connect it to other pins such as rx and tx, you will have problems. Do not get energy from esp8266, you need to provide external 5v for the relay.
Nice circuit. Love that there is no wires under the circuit. Can i replace just the 5v relay with a 12v one and just supply seperate 12v to the module and connect the trigger pin to arduino?
Great video. Is this called a relay driver? Also, what if you wanted to electrically separate the relay. Say you were going to run the coil with 5V and the common with 120V AC? How would you configure?
After that i connected, after that i connected, after that i connected, after that i connected, after that i connected... Why did you connect? Explain the circuit dude.
I made same circuit but problem is that my green led is glowing opposite condition. In initial position it is on and after trigger is goes off. I tried many things like- 1. Changed Transistor direction 2. Changed diode direction 3. Changed both components But not getting proper Solution 😔😔
maybe led red need to switch, the best position is resisistor 100 ohm and then led , not opposite, to avoid 5 volt direct to led, for long life pcb, correct if i'm wrong.thanks.
Why is the transitor & 1k resistor required to energize the relay's coil? In your test of the circuit (approx. 8:21 when you connect your signal input to the constant 5v+) the transistor & resistor don't appear to have any benefit vs simply connecting the signal wire directly to the relay's + coil terminal. Is it because ultimately your using the Aduieno to control the circuit and your protecting the Aduieno circuits or are they not powerful enough to activate the relays coil? It just seems like the transistor/1k resistor are just extra pieces in the circuit.
To resistors are used to make sure that the led don't burned out or get fused becauae its 5 volts and by using the resistor the volt will be less than 5 volts to safely turn om the leds
You should NEVER use a solder bridge to conduct high currents. It is not safe. Use a wire and pinch the connections around the relay NO, NC, & Common pins and around the terminal block pins. Then use the solder to keep each connection from separating. The current needs to flow from wire to contact and NOT through the solder.

Just a tip --- you can technically bend the leads and solder them instead of using globs of solder to connect the lines/traces.
Still a cool video
Instead of using solder bridges, why not simply use scrap leads from your resistors. The result will be neater and probably more reliable.
Your colourful diagrams with name
It becomes very easy to understand
I have solved it it has built in diode mini relay TQ2 I use mini malt shortcut smd transistor BC847 & 1K SMD! Works 10000%
fantastic video
Best video.
❤I like to see a 12v relay with 16 amp circuit board 😊
Very informative video. Very helpful.
Thanks for this a simple modul relay 5v
This is a great video. Thanks for sharing.
Exactly what I needed. Thank you friend! 👍🏼
*Wonderful video. Great project. It's always needed to interface relay to such controllers.*
Thanks after see your circuit diagram and video i will make it successfully
Working perfectly.
Works very good!! Thanks
Great video, thanks!
Nice circuit. Love that there is no wires under the circuit. Can i replace just the 5v relay with a 12v one and just supply seperate 12v to the module and connect the trigger pin to arduino?
Yes
Which software did you use to make the circuit diagrams?
Will it work if I connect Capacitive touch sensor direct to it?????
Which software you are using for circuit displaying......
This circuit activates the high signal?
Thanks mere bhai
Great video. Is this called a relay driver? Also, what if you wanted to electrically separate the relay. Say you were going to run the coil with 5V and the common with 120V AC? How would you configure?
Then use opto coupler
good job! thanks
can i use 1n4001 instead of 1n4007?
Will it work with nodemcu 3.3v input
After that i connected, after that i connected, after that i connected, after that i connected, after that i connected... Why did you connect? Explain the circuit dude.
is pin 1 the collector of the transistor?
What software did you used to demonstrate circuit connection ? Please reply bro
ms power point
@@KiyanisLab really . It's awesome . Great work . Keep doing. I'm a fan from Pondicherry .
Sir,this is module what is type low or high triger?tks for answer
Can you build a project that starts a lawn mower from an RC Controller?
yes if motor current is less than 5 amps for more amps use bigger relay with same circuit
Can you make a relay module using optocoupler? thanks in advance
How come you changed the LED resistor between power & ground?
Kalo relay 12volt apa tetep sama komponennya?
can i substitute a BC337?
does this work with 3.3v input?
yes it does
Super kiyanis 👍👍👍👍👌👌👌👌🤝🤝🤝🤝🤝
I made same circuit but problem is that my green led is glowing opposite condition. In initial position it is on and after trigger is goes off. I tried many things like- 1. Changed Transistor direction
2. Changed diode direction
3. Changed both components
But not getting proper Solution 😔😔
Thanks bro your circuit worked pretty well.
Can I make same circuit for 9v battery?
What is the programm for design circuit?
Really amazing video !
Work it 12 volt relay?
yes use 12v relay and 1k resistors for leds
💛💛 thumbs up..!! one request ..... pls do a experiment for a reliable zvs driver circuit(for cathode ray experiment)
How to operate with remote control please tell me
Show de bola prof. Obrigado!
maybe led red need to switch, the best position is resisistor 100 ohm and then led , not opposite, to avoid 5 volt direct to led, for long life pcb, correct if i'm wrong.thanks.
right
Amazing
¿are the leds just for visual information?
yes bro
Do i need coding for arduino?
Bro pls put a video about creating power bank charging module for 3.7 v rechargeable battery
What is 330 resistor in the diagram
Good
What is the transistor for? Is it related to the current values of the input and output voltages?
transistor is to drive the relay with lower voltage and current eg output of a microcontroller
Pls pls pls reply what are the 1,2 and 3 pins in the transistor
1 collector 2 base 3 emitter

he used transistor to operate relay below 5v... relay below 5v wont work but transistor will
12v relay not work I made for this circuit diagram why ?
Maybe the resistor values will need to change.
Please make 12v relay module
Can i give ac current
Hello boss... How about the coding? Can we know about the coding please
Thanks bro

Sir please make bluetooth based home automation with display using aurdino
I made it , tested it, clicking sound is coming but there is no output voltage. What to do. I eaven checked my relay. It is not damaged
Please help
You did something wrong? When the green Eli D turns odd the red should turn off if the switch is moving
This video is true
What is the minimum signal volts?
3v
Why did you used Arduino at last?
Do i need a code for Arduino?
i just show how we can use it with Arduino yes Arduino need a code to run
Hii sar echo carkut ke bare me vedio banao ya fir mujhe bata do
More than video upload sir
sir relay ke Saath diode Kyu lagate hai aur kabhi diode ke Saath capacitor bhi lagta hai.iska Kya function hai detail mei hindi se bataiye.
g bhai video banata hu is pe
Osammmmmmmmmmmmm
Bhai ambulance light flasher bao please
Ardunio module circuit ready panuga bro
Why did you add a diode there
its a flyback diode for the relay coil
Without diode.. you burn transistore
Sir pls send the Gerber file of this🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
This is not optically isolated
