In many electronic devices, we need a way for users to interact with them. One common method is using touch sensors. These sensors are essential in connecting users to microcontrollers like Arduino, simplifying data input. Touch sensors have various applications, from mobile phones to LCD monitor switches. Among the available options, capacitive touch sensors, particularly those based on the TTP223 driver IC, are widely used.
Capacitive touch sensors using the TTP223 IC operate between 2V and 5.5V, with very low power consumption. They offer an affordable, energy-efficient, and easy-to-integrate solution, making them a popular choice in the world of capacitive touch sensors.
