control dc motor with relay


New Member
hello! how i create a control dc motor with relay. i would like control the rpm to dc motor, but i use relay for this motor.
also where i put the pin of this relay? in pwm pin or digital pin?

thank you!!!

Relays is incompatible with pwm.

To use pwm to control a dc motor you'll need something faster, typically a transistor.

can i put tranzistor previews the relay and after the motor?
Please rephrase or make a scetch to depict what you're thinking on.

Whatever you're meaning - since you're mention relay in same sentence - probably no.
