In this video I’m going to show you how to create a nice touch controller for your light setup. Using a voltage regulator to control the brightness and touch sensor to turn it on and off, you can build an awesome controller to turn on and off your lights or any other DC powered unit.

This one is a very simple but cool project, something that I would recommend to anyone who is interested into DIY electronics, gadgets and learning new stuff in general. It is definitely one of those projects that don’t require too much time but you can learn a lot by making it and also earn a lot of credit by sharing it with your friends and family.
Below you can see a final product. It’s a heart shaped, touch sensitive, keychain for your loved ones. On the front side there is a smiley face drawing that has eyes and mouth. Eyes have two red LEDs that will start to pulse once you touch the keychain or place you finger on the smiley face (see it in action below)

Heartbeat key-chain is intended to be a small gift that your loved one can carry with her/him wherever she/he goes.
Basically top side of the PCB is touch sensitive and has one RGB LED. When the exposed copper on the top side is touched, the microcontroller detects it and begins to pulse the LED in the heartbeat like pattern.
Bill of material, schematics and source code are available on GitHub.
I am posting render images of the PCB since I’m waiting for the Fab house to manufacture the boards for me.
