Code and Wiring

We made this setup for simple variable speed of a 12V DC motor using a potentiometer. The accompanying code is below. Now we have to figure out how to configure this type of setup to work with four motors hooked up to a motor shield in such a way that the motors on same sides run together and have each side run independently ( two joysticks).

int potPin = A0;

int motorPin = 9;

int potValue = 0;

int motorValue = 0;

void setup() {

 Serial.begin(9600);

}

void loop() {

 potValue = analogRead(potPin);  

 motorValue = map(potValue, 0, 1023, 0, 255);

 analogWrite(motorPin, motorValue);  

 Serial.print("potentiometer = " );     

 Serial.print(potValue);

 Serial.print("\t motor = ");

 Serial.println(motorValue);

 delay(2);    

}
