My 2 cents. "unlimited useless components" is simply not true (after all, the Chinese manufacturers are always looking to cut down to the minimum number of components). An optoisolator is the best example of something really useful and really important when switching AC. Totally agree with you when we're talking about switching LVDC, but most relays have an AC rating on them too. I also agree that the LEDs can be totally excessive for most projects.
sir i spent a lot of time building this following the animation circuit and now at the end you created a different version which i love more. but i am a beginner in elec and i want you to point out the connections for me using the animation having two LED that you used
I came here as I wanted to see someone make a relay component module by wrapping wire, rather than making the relay module BOARD. But I liked the nice animations so it wasn't a waste of time!
Wrong The led connected to the common will turn on when the circuit it complete. This happens, when the armature connects to the NO pin of the relay. There is, however, a little visual issue in the diagram. The positive leg of the led, which looks like it is connected to the common pin, is actually connected to +ve..
I am at beginner level, have a confusion at 3:15 - there are 3 wires at the left side, red wire to 5v dc, black wire to ground & there is another wire as ash color, with which i am supposed to connect that ?
@@harisuresh2507 So for using it with arduino, i have to connect red wire with 5v, black wire with ground & Ash colored wire with any digital pin to make it HIGH/LOW, for turning the device on/off AM I RIGHT ?
Same setup Use a 5V voltage regulator or if you're looking for something simple, just throw in a zener diode in reverse bias. Check out this discussion: electronics.stackexchange.com/questions/127525/reducing-voltage-with-resistors
How to switch it on with them cheap mx-rm-5v or i have the better rx480e-4a but i would prefer to use the mx-rm due to cheaper cost but it goes high then low causes my garage doors to open while i am at work iv tried time delay but its just becoming over engineered it should be as simple as sending a high to a NPN but if it always goes high on power up this will trigger relay or on a reset everyday
They will but, If you are not aware of "Inductive Kickback" then you will very soon kill your microcontroller. Remember: It is very important to place a diode across the coil of the relay because a spike of voltage (inductive kickback from the coil) is generated (Electromagnetic Interference) when the current is removed from the coil due to the collapse of the magnetic field. This voltage spike can damage the sensitive electronic components controlling the circuit. Note: Short circuits on Arduino pins, or attempting to run high current devices from it, can damage or destroy the output transistors in the pin, or damage the entire AtMega chip. Often this will result in a "dead" pin of the micro-controller but the remaining chip will still function adequately. For this reason it is a good idea to connect OUTPUT pins to other devices with 470Ω or 1k resistors, unless maximum current draw from the pins is required for a particular application To know all about relay, checkout my blog post: diyfactory007.blogspot.com/2018/04/driving-relay-with-arduino.html
I would have never thought of doing this myself. Thanks for the tutorial.
Cheers
I built this on some perf board today and it works perfectly! Thanks, man!
Well done 👏
good job. do you used high-level-trig? how to use it low-level-trig? thanks.

Agreed
I realize I am kind of randomly asking but does anybody know of a good site to stream newly released series online?
Hello my friend.
Do it yourself is a beautiful role model. Thank's for the information. See you. big greetings.
Thank you! Cheers!
@Gerardo Gage 👏👏👏👏👏
Very good Diy Relay Module tutorial
Easy as
Good job mate
Posting videos very frequently these days.
Yeah thanks
Many thanks for the information, very easy to follow. I have subscribed.
Thanks
thanks for this video amazing
Glad you liked it!

Nailed it brother

Ha ha ha, you solved my problem.
Also JLC is the best.
I am going to order few of these from them
I know, thanks again
Great video just built this❤️
Well done mate
Well done again
Excellent video, I am a little new to this, what would be the difference from using a diode to an octocoupler?
Unbelievable your the best.
Cheers mate
3:23 trigger LED should be on +ve and collector of the transistor not in the COM & NO pin which suppose to be AC line genarally
Wrong
The led connected to the common will turn on when the circuit it complete. This happens, when the armature connects to the NO pin of the relay.
There is, however, a little visual issue in the diagram. The positive leg of the led, which looks like it is connected to the common pin, is actually connected to +ve..
Thanks, very useful But those wires are not called twisted pairs lol.
Oops, ribbon cables
Damn.. ha ha
I am at beginner level, have a confusion at 3:15 - there are 3 wires at the left side, red wire to 5v dc, black wire to ground & there is another wire as ash color, with which i am supposed to connect that ?
positive of your battery
That is correct.
It is a NPN transitor so the base connects to the +ve
@@harisuresh2507 So for using it with arduino, i have to connect red wire with 5v,
black wire with ground &
Ash colored wire with any digital pin to make it HIGH/LOW, for turning the device on/off
AM I RIGHT ?
@@sohan2510 Yes.
@@harisuresh2507 thanks brother ♥️
If i want relay with delay can u explain to me
my upcoming video is on that topic only.
Please stay tuned
@@CrazyCoupleDIY ok
Can i use 12v relay and power it using 12v?
Yes, of course
I wonder if the same components can be used for a 3v dpdt relay?
Yes
The idea of animating current and explaining the work of module is good, but the realization is very poor. Its for those who already understands.
How do I do a 12v?
Same setup
Use a 5V voltage regulator or if you're looking for something simple, just throw in a zener diode in reverse bias.

Sorry I am a bit confused
So what are you trying to achieve?
What's the scenario?
can use same setup with a 12VDC relay?
Absolutely
I have always ordered my stuff from JLC PCB
Hey the gerber file doesn't want to download
can you fix that please
Apologies for the inconvenience
I have just uploaded a copy to the google drive.

@@CrazyCoupleDIY Hello is it the same gerber file in the video please ?
Apologies that was my bad.
The correct one is this one: drive.google.com/file/d/1nTqW5lt4LXGkdkpmn_hwBVQSUMnZm7Y9/view?usp=sharing
I can't download a gerber file. Can you upload it somewhere else?
Sorry about the inconvenience
I have updated the link and it should work now
And thanks again for watching my video
Easy as
where the gerber file??
Link is in the description below
Why is the diode required at all?? I use them without diodes and they work just fine
