Make your own Capacitive Touch Sensor with Arduino

Instructables user “timbit1985” was tired of fumbling for the bedside light switch in the middle of the night, so he instead created a capacitive touch sensor that can be used to control LED lights or other devices. Although it sounds complex – doing so is relatively simple and inexpensive. The sensor surface can be almost any metal object, and in this example it’s part of the enclosure. Finally to save money they’ve used a standalone microcontroller with the Arduino bootloader. A quick demonstration is contained in the following video:

 

To make your own touch-switch, visit the project page. And for more, we’re on twitter and Google+, so follow us for news and product updates as well.

  

 

If you’re wanting to reproduce the project above – we’ve got you covered with our new ATmega328P MCUs with Arduino Uno bootloader:

This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our ElevenEtherTenUSBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board. Comes with the Arduino Uno bootloader pre-installed. Better still, it even has a special label stuck on top with details of the pinout, so you don’t even need to look up the datasheet when connecting it up in your project!
