I had to teach Arduino and Raspberry Pi at a Korean American Science and Engineers Association's annual meeting called Ygnite. While prepping, I thought why not I bring live samples of Arduino and Raspberry Pi. However, given the typical classroom environment, those live samples have to be passed around Students who are seated. Typical samples are complicated shapes and wires, so it is hard to pass around.
My idea was putting those samples on writing pads. So I installed projects on writing pad, and those projects could be quickly and easily passed around among the 50 students who took the class. Also, the projects are set on A4 paper, so written descriptions could be implemented right next to the individual components of samples for Arduino, Raspberry Pi, and IOIO OTG . Anyways, the samples are shown below.
