Read a potentiometer

In this lesson, we will add a potentiometer to our circuit. Make these connections for a slide potentiomter

[ ] GND on the potentiometer to ground on your breadboard

[ ] VCC on the potentiometer to positive voltage on your breadboard

[ ] OTB on the potentiometer to A0 on your microcontroller

void setup()

  pinMode(2, OUTPUT);

  pinMode(3, OUTPUT);

  pinMode(4, OUTPUT);

  pinMode(5, OUTPUT);

int position;

int delaytime;

void loop()

  delaytime = analogRead(0);

  digitalWrite(position + 2, HIGH);

  delay(delaytime);

  delaytime = analogRead(0);

  digitalWrite(position + 2, LOW);

  delay(delaytime);

  position = position + 1;

  if (position > 3)

    position = 0;
