Product review & video
did you ever have one of those projects that got just a little bit out of hand i have hey everybody i hope you're having a fantastic day i have been asked several times how many relays can i connect directly to one of these mega boards without blowing the thing up well i am about to find out now before i get started i want to say that although i've hooked a fair number of relays directly to arduinos without problems and ran them for years my favorite way of doing it and the way that you should do it is by using external power on the relay boards now my favorite way to accomplish that is to take an old usb cable this is an old micro usb cable and i took the power and ground lines of the usb cable and what i like to do is find these cheap this is a samsung clone charger and i actually use one of these to power the relay board and use the other one with the usb cable to power the arduino n
