This video is extremely well done, you explained it well, demonstrated it with a nice simple demo, and pointed out that it fires on Low and showed a great technique for that. I really appreciate the work you put into this, and wish I'd watched it before fighting with the relay for 2 hours last night (I was assuming high triggered it and thought I had a signal issue...ugh). Subscribed and will check out the rest of your videos!
Can someone help me? I need to control 4 relay with a 4 axys joystick. On position 1 of the joystick, 3 relay need to be on. On position 2, 2 relay need to be on. On position 3, 2 relay beed to be on. On position 4, one relay need to be on. Those relay will control some hydrolic valve...
Hi, I have made a similar project with the same relays board. When I power up the Arduino the 4 relays go on and off really fast until the arduino set everything up. There is a code formula to stop it? Or It's because I'm powering the relays board directly from Arduino without the additional power supply? thank you so much!

Have the same relay and thought it wasn't working but just didn't realize that it's triggered on LOW. Thanks for the help!
Thanks Bro. Thought my module was shot. Great video, well explained. My project is working like a dream.
This was a good demonstration and was helpful to me. This made it clearer than many other videos I have watched. Thank you for posting this!
GOOD JOB
This is fantastic. Great explanation of exactly what I was looking for
This really helped me with my project! Thanks!
Very good video. 👌
Needed this. Thx
What resistance did you use in your video? Thanks!!!
Thank you very much.

I can't get the code to work. Why I try to upload it immediately flags the second line and says "'relay' does not name a type; did you mean 'delay'?"
Hi nice work I want the led to light up one by one and then inplace of turning off I want it to remain on . What to do plz help

keep it up
great thanks,keep it up.
Good day. I was trying the code you wrote but i cant get it to work. I get stuck on the second line.
the resistors which are used here are they of 1kOhm?
nice
So that's why I thought the yellow thing was a safety pin and remove it first to work, turns out other way around
What power supply do you have plugged on your Breadboard?
I used 5v power supply since it was just for demonstration. However the relay can use higher voltages like 220v . But be careful not to get shocked!!
