The TTP223B capacitive touch sensor detects touch or proximity. It operates by measuring changes in capacitance when a conductive object, like a finger, approaches its surface. This sensor is commonly used in various electronic projects and can be interfaced with microcontrollers like Arduino to create touch-sensitive interfaces or control systems. In this tutorial, you will learn how to interface the TTP223B capacitive touch sensor switch with an Arduino Uno board. This guide includes all the necessary components, pin description, wiring connections, and Arduino code.
