Turn Your Lights on With Clapping?!

Wouldn't it be nice to turn on your lights without getting off the couch? In this project I am going to show you how to build a simple Arduino clap circuit which can turn on and off all kinds of AC appliances. Let's get started!

The video gives you an overview on how to build this project. But I am going to present you more detailed information in the following steps to make your life easier.

Visit your local hardware store to get your screws, nuts and different connectors.

Here you can find the schematic and veroboard layout to create your own clap circuit. I recommend to build it firstly on a breadboard to test the circuit before moving it over to a stripboard.

Use the given sketch to program your ATtiny85. If you don't know how to do this with an Arduino Uno then have a look at my previous video about the subject:

With the help of the pictures you should be able to see which wire connects to which connector. As I mentioned in the video 230V can kill you, be careful!

You did it. You just created your own clap circuit!
