How to use a relay, the easy way

Thanks alot man. I'm making a project about Arduino and had to make my own PCB with on board relay switch. This really helps me alot.

You should really clearly show where every single wire is feeding in to the relay so one can see very clearly where each wire is at. For instance the wire the you use as switch, in and out, where is the other end of it? On the end you are showing seem to be going to positive. What about that wire next to it. What is that wire and where is that going, positive to...? And is everything hooked up to 12 volts DC or? where is the power coming from? Are you feeding AC and output DC and trigger is how many volts? Are there three different voltage feeding?

LOL, I had headphones on, and I turned the volume up so high because I could not hear him, then I went to another video after I was done watching it, and the music was so loud that I almost broke my headphones from hitting my head on the chair at full speed, and nice video by the way :)

Thanks man. I was working on a difficult project and this really helped!

awesome tutorial... explained in a clear and concise manner... and the pronunciation is very good ...

Thanks a lot for your video man !

Great Video Dude. Very Helpful. Keep up the great work. Nick.

thanks man good explanation !!!

thanks for keeping it short and simple

My relay is a Songle 5VDC relay and when it clicks, it gets satisfying. Overall, thanks for the video.

Good vid, thanks 👍

hi there good work ,, does ac coil relay work if i supply it with a dc supply and vise versa? thank you

i have a question, i build a tube guitar pedal and in the stecs is a relay 12vcd 2x um, can i use this directly or did i have to find out the amper?

Good video. Thanks for that.

Helpful, thanks!

can i get the same output of 12 v when i give an input voltage of -5v if the relay was a 5v switch with output of 12v.

Maybe I didn't follow well enough, but would this circuit (or a variation of it) allow me to use a push button momentary switch to begin running a machine of mine that would shut itself off and not start up again in the event of a power failure? So in other words, N.O. push button closes a N.O. relay and then, as long as there's power running to it, the relay stays closed.

Hi, i have a relay and when i shake it, it make a sound, like if there is something moving in it. Is my relay break because i can't test it. Thanks !

have you thought about putting a photo resistor into your circuit. When it becomes dark have the photo resistor turn on another circuit through a transistor? I'm not too sure what you mean?

One of the nice project,really!!
