The circuit attaches onto an ardunio uno which will be programmed to control the digital potentiometer which will change the voltage going into the motor threw a buck converter, the motor is shunted to mesure the current passing threw it.

The circuit is meant for a small car that has a small power source and I needed as much power as I could get.

Controlling a motor by varying its supply voltage is not usually the best way, because the speed will vary according to the load. PWM is a more efficient method, with the duty cycle varied to maintain a desired speed if required.
