These 2 above tutorials run through the basics of creating circuits on the Raspberry pi. The first video shows how to make circuits without specialized equipment and an optional breadboard. The second video is a more advanced tutorial on how to use GPIO extension tools with the raspberry pi. Unsurprisingly, creating circuits on the pi was very similar to the circuits we created in CPE 390 and CPE 487.
The video below is a step by step narration of building an Ethereum (ETC) blockchain node on the Pi. This is a but outside the scope of the class but It relates to some of the later labs we've done in this class especially lab 10.
