[Reply #1 on:]

starter ... connect switch to pin 10 and LED to 13 (add resistor 220 ohm)

Code:

void setup()
{
  pinMode(10, INPUT);
  pinMode(13, OUTPUT);
}

void loop()
{
  digitalWrite(13, digitalRead(10);
}

go to examples/basic/blink in the Arduino programming environment...that's what it's there for

Code:

digitalWrite(13, digitalRead(10);

Close...but no cigar.
