TINKERCAD
1.Calibrate the rotary potentiometer to get angles in degree ?
2.Control DC motor speed using PWM.
3.Attach the DC motor & potentiometer, and control theangle of the DC motor.
•Proportional control = error * Kp
•Use the calibrated potentiometer code and control dcmotor code to get this task done.
