During normal operation, the touchshield needs: +5V GND During TouchShield programing of the TouchShield uses pins: Arduino +5V Arduino GND Arduino Reset Arduino 0 Arduino 1 When the touchShield is talking to the Arduino, the TouchShield uses: Arduino +5V Arduino GND Arduino Reset Arduino 2 Arduino 3 Pins 12 and 13 can be used for anything… but typically they don’t do anything.
