This Arduino code makes a simple touch counter. Every time the touch module TTP223/TTP223B is touched, the counter number increases and displays on the LED display TM1637 and on the serial monitor in Arduino IDE by pressing Ctrl+Shift+M on your PC. There is a reset button with which you can reset the counting at any time.

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