hi, i have been working on this circuit for a while and i was wondering if someone could have a look at it to see if it will work

I have no idea what it's even supposed to do?

 

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.
