A good start would be to check if you can read the two inputs and display the values.
Code:
#define Potentiometer A0
#define Battery A1
void setup(){
Serial.begin(115200);
}
void loop(){
int32_t ADC;
ADC = analogRead(Potentiometer);
//change to mV
ADC*=5000;
ADC/=1024;
Serial.print("Value from pot = ");
Serial.println(ADC);
ADC = analogRead(Battery);
//change to mV
ADC*=5000;
ADC/=1024; //now 1/3 of actual battery voltage
ADC*=3;
Serial.print("Value from battery = ");
Serial.println(ADC);
delay(500);
}The above should display the two voltages on the serial monitor.
If this works then we can look at turning the motor on.
