     * This is the Arduino code for TTP 224 4 Channel Capacitive Touch switch 
     * the output pen 10, 11, 12 and 13 will be ON when key 1 to 4 are pressed respectively
     * pressing button 1, Turns pin 10 ON
     * pressing button 2, Turns pin 11 ON
     * pressing button 3, Turns pin 12 ON
     * pressing button 4, Turns pin 13 ON
