hi guys
I am trying to build an arduino based radar car and I want to use a DC motor
connected to a relay to control the movement of the car but I
don't kow how to interface the relay to the DC motor and how to programming it.
I will be grateful if someone could offer help coz i have searched for a video on you-tube
and I haven't seen one.Thanks guys I'll be waiting

 

There HAS to be some links out there that you can go from!
BTW relay motor control only achieves on/off (stop/go) not speed control if that is what you are looking for.
Max.
