This Arduino code make simple touch counter. Every time touch module TTP223/TTP223B is touched, the counter number increases and displays on the LED display TM1637 and on serial monitor in Arduino 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.

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