/*
 * This is an Arduino Robojax Touch counter using TTP223/TTP223B.
 * This program will function as a counter. Every time the touch module is touched,
 * the counter increments by 1.
 * We have a reset button to restart the counting from zero.
 * 
 * Watch video instructions for this video: https://youtu.be/zJ-yd4vYn8s
