Interfacing4-Channels Capacitive Touch Module with Arduino

/* This code works with 4 channel Capacitive touch buttons module or 4 buttons/switches and a RGB LED
 * It controls the colors values of a RGB LED and displays the current values on the serial monitor
 * Refer to www.SurtrTech.com for more details
