hi do you have more details i would like to do the same but with a relay of 8 or 15 output

this relay module doesnt actually work like that ,hes alluding to the fact that the relay works like a flip flop,but it doesnt ,it takes a 5 volt digital signal from a mcu to trigger it ,you would need whats called a Bistable flipflop relay switch with negitive trigger,not mcu trigger cheers

Any detail available for me

3d animation video please...

its negative trigger

Hello sir, how to control ac 220 motors use this 5v realy

Components

what the sound is this?

Maximum signal voltage??

Might be a dumb question, but does that mean a 5v relay takes in 5v and a 12v relay would take in 12v? Not that the relay is rated up to 5v?
