This project demonstrates a simple embedded system that uses a touch sensor to control an LED. The code is written in Embedded C for an Arduino Uno and compiled using the Arduino IDE. When the touch ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

This project demonstrates how to use an ESP8266 microcontroller with a capacitive touch sensor module to detect the presence of metal objects. The sensor module outputs a digital signal that changes ...
