Welcome to the Raspberry Pi Workshop Tutorials, brought to you by ModMyPi, BuyaPi.ca, and PiShop.us. In this series, we’ll demonstrate nine projects that can be made using the YouTube Workshop Kit for Raspberry Pi. These projects are a great way to familiarize yourself with the Pi’s input and output functions, as well as creating programs in Python that we’ll use to control the Pi’s hardware.
