The Arduino Starter Kit Project 2- Non LED-light

[TomGeorge]

Hi, @janosch1
Connect the green led wire back to pin 3 and try this code;

int switchPin = 2;
int greenledPin = 3;
bool switchstate;

void setup()
{
  pinMode(switchPin, INPUT);
  pinMode(greenledPin, OUTPUT);
}

void loop()
{
  if (switchstate == LOW)
  {
    digitalWrite(greenledPin, LOW);
  }
  else
  {
    digitalWrite(greenledPin, HIGH);
  }
}
