This Arduino code makes a simple touch counter. Every time the TTP223/TTP223B touch module is touched, the counter number increases and displays on the LCD1602-I2C display and on the Arduino serial monitor by pressing Ctrl+Shift+M on your PC. There is a reset button with which you can reset the count 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.
