For braking lights (attached to same pin as they turn on at the same time) By the LabVIEW aided PID controller, the parameters are adjusted to control the motor speed. #define SCALING 35128.6 //Motor speed scaling Thank you in advance to anyone who takes the time to help! //pid motor control with input The PID controller is a general-purpose controller that combines the three basic modes of control, i.e., the proportional (P), the derivative (D), and the integral (I) modes. Can anyone see where I have gone wrong in my code? What I expected from the code was to input a value to set the speed of the motor and to then make it react to the Ultrasonic sensor. Since I have done this my value for my actual speed stays as 0 and I can't see where I've gone wrong as I am quite new to this.

My code was working fine when I set the speed with a potentiometer but I have changed it to map(input,65,90,-255,255) so I could input a value from A-Z into the serial and this would control the speed of the motor.

I am trying to simulate comms with LabVIEW from Tinkercad( as I don't own an Arduino board yet).
