RoboJax Touch Counter V3 Verwendung des TM1637 4-stelligen LED-Displays

/*
 * This is Arduino touch counter V3 using TTP223/TTP223B and TM1637 seven-segment LED Display.
 * This program will function as a counter. Every time the touch module is touched,
 * the counter increments by 1. The count number is displayed on the TM1637 display.
 * We have a reset button to restart the counting from zero.
 * 
 * Watch video instructions for this video: https://youtu.be/VzH9iEqrm0E
