void setup() {
  pimMode(switchPin, INPUT);
  pimMode(led1Pin, OUTPUT);
  pimMode(led2Pin, OUTPUT);
}

void loop() {
  int switchVal;
  switchVal = digitalRead(switchPin);
  
  if (switchVal == HIGH) {
    digitalWrite(led1Pin, HIGH);
    delay(500);
    digitalWrite(led2Pin, LOW);
    delay(500);
  }
  
  else {
    digitalWrite(led2Pin, HIGH);
    delay(500);
    digitalWrite(led1Pin, LOW);
