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 are in need of special present motorists. Motor relay board comes in to the photo due to these demands. Engine relay board drives engines and relays by providing adequate present. It may drive one relay and four DC motors or one motor that is stepper a time. The engine relay board eases the duty of interfacing motor that is external AC products utilizing the ATmega32 microcontroller. This has ULN2003 motorists for high applications that are current motor driving and relay driving circuits for AC unit interfacing.

You can find three main parts for a engine relay board.

Relay Motorist

Utilizing the supplied relay circuit, 230V devices may be managed. This part is useful for automating the on / off.

Engine Driver

The DC engine could be managed by using this area, there was 4 driver that is ULN2003 lines for driving engines and every provides adequate current to manage the DC engine.
