Engine Relay Board Hookup Guide. As gear like engines and relays need high present, microcontrollers cannot drive them.
to be able to drive them, we truly need unique present motorists. Motor relay board comes to the photo due to these demands. Engine relay board drives engines and relays by providing adequate current. It may drive one relay and four DC motors or one stepper motor at a time. The engine relay board eases the task of interfacing outside engine and AC products aided by the ATmega32 microcontroller. Continue reading
