Wa-la sir, NOW I understand relays. I could not find anything else that told me what the 3 terminal posts were (per relay), on the far side of the relay. Thanks, well-explained.
Glad to hear, thanks for watching!
Very interesting information! Excellent presentation!
Thanks!
Very helpful video. Thanks a lot for posting this!
Thanks for watching!
Finaly someone was ably to explain this simple topic in not over engineered form👏
Thank you for the explanation! :D
Thanks for watching!
Thx for your video keep going ✌🏻
Thank you!
interesting explanation
Thanks!
Good Video, I would like to know the same info but on the jumper side of it, You never talked about that part.
Ok but do you need to set the output voltage for DC circuits? I have the same 5v, 2 channel relay that I am attempting to power from a independent power supply to control a 12v Fan, and a 5v Temperature Sensor with.
Holly crap I didn't know Norm McDonald knew electronics! RIP
Yeah, sad that he is gone now :(
@@Electronzap yeah you really do sound like him. Bet you hear that often .
Oh BTW there are some offset standoffs that are plastic that you might wanna look into. I got some and love using them. I think they are called video game console standoffs. The screws they come with have large heads and can't be used with these small relay boards. Had to go to local screw and dolt place and get a few hundred for 3 bucks. I'll link to video where I used them and find what size screws I got when I get back in town.
@@AztecWarrior69 I've been told that I sound like Norm for over 25 years now lol. I was surprised nobody mentioned his passing sooner.
Thanks... I have a question, can I use different power supply to trigger the relay? I saw you use negative from same ps to switch the relay, I am thinking to use a different supply to trigger it, is that possible?😊
The relay coil is all that gets powered. The switch part of the relay can switch a completely different power source.
Question : so to measure current used by switching operation, I should break the 5V to Relay's VCC connection ?
Almost all of the module's power should be for the relay coil. Just a little current is needed for the circuitry. So, I would just measure the whole current of the module when it is switched.
so that means...if the relay is a low trigger type... when I use the contacts (com no)...the load must be connected to negative supply..right? also, is it possible if the load is supplied with 12v while ground is connected to the ground of arduino?
The switch part of the relay is just a mechanical switch. A magnetic field is what moves the switch position. None of the electricity from the module makes it to the switch part, so you can wire up a load however you normally wire it up to a mechanical switch.
@@Electronzap im still confused..still wont work for me..i followed the video only to replace the led with 12v solenoid lock...i expect the output would be like the led but it wont work
Generally battery ranges are 1.5 v or 9v..can we power it 9 volt or 2x1.5 v to the relay
You'd have to check the manufacturer's specifications before you buy a module to see what range of voltages you can use.
electronzapdotcom thanks
Say I had a roller door that has auxiliary output that pulse for one second when button pressed how could you connect that to this relay to switch a light ?
Not sure, and this is probably not a bad relay for that. I'd try to find a relay made for that and follow their guidelines.
Oops, I meant to say that this is probably a bad relay for that.
electronzapdotcom yes, I have been trying to find something other than a pic that would work , issue is with the signal being pulse on for 1 second. I have tried 2 transistors using caps to toggle but was unreliable.
Yeah, sounds like a tricky circuit to design.
can it switching until 50 times per second (50Hz)? I mean 10ms ON and 10ms OFF (delay)
No clue, you'd want to check the specifications, but these are mechanical switches, so I don't think you'd want to switch it near that much.
ok thanks, ill search on google
