TTP224 4-ચેનલ ટચ સેન્સર રિલે સાથે AC/DC લોડ ચાલુ કરવા માટે

/*
 * This is the Arduino code for TTP224 4-Channel Capacitive Touch switch.
 * The output pins 10, 11, 12, and 13 will be LOW when keys 1 to 4 are pressed respectively,
 * and the connected relay will go ON.
 * Pressing button 1 turns pin 10 LOW.
 * Pressing button 2 turns pin 11 LOW.
 * Pressing button 3 turns pin 12 LOW.
 * Pressing button 4 turns pin 13 LOW.
