This is the Add-On kit for the SparkFun Digital Sandbox (DS) learning platform. With this add-on you will be able to perform the final three circuit experiments found in the DS Guide book which include making an electric musical instrument, telling a motor to spin as fast as you want, and controlling a servo. This is the perfect kit if you\'ve completed everything to do with the Digital Sandbox but are looking for more!
**Note:** If you are looking for the first 13 experiments they can be found with the [Digital Sandbox](https://www.sparkfun.com/products/12651) learning platform.
