Robojax Touch Counter V1 (basic counter)

This Arduino code make simple touch counter. Every time touch module TTP223/TTP223B is touched, the counter number increases and displayed on the serial monitor in Arduino. You can view Serial MOnitor by pressing Ctrl+Shift+M on your PC. There is a reset button which you can reset the counting at any time.

TTP223 or TTP223B module with a single push button is used to make this counter. Any Arduino boards can be used.

Resources for this sketch

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