May I dumb this discussion down a bit?
I would like to control several small AC and DC motors in my project. Currently I am using a Mega with a multi channel relay module like this:
All I do is switch relays to turn on and off motors. It all works but I think, to the subject of this thread
(Mod edit: Flyback diodes and why you need them (comments here please)) I am causing issues when I turn off motors as I need to periodically reset my mega. Initially I wasn't concerned because the relay board is optically isolated and the motors are small but after reading this discussion i'm not so sure... How would I size flyback diodes based on motor specs? What about AC motors? Maybe this was addressed earlier but the discussion got real deep, real fast and lost me (thanks smaj )
This is my first ever post on any forum ever so if i'm in the wrong place, broke a rule or just out of line please be kind...
