hi everyone, i am a mechatronics engineer with a graduation project that turned out to be an electrical engineer project! my project is a prototype of a solar car, i did all mechanical calculations but lost on how to :
control remotely : 1)the direction of DC motor
2)the speed of dc motor
i should finish this in two weeks! please help me, any tip would be most appreciated
thanks a lot in advance.

H-Bridge and PWM - however, depending on the power requirements, it may be far from simple!.

A quick and dirty answer:

To control the direction of rotation of a DC motor, reverse the supply connections.

To make a DC motor turn faster, increase the supply voltage.
(And to slow it down, reduce the voltage)
