Arduino [ simple input / output microcontroller board system] was born, and rapid prototyping became familiar. Rapid prototyping is changing to literacy over the past decade. The skills to master complex technologies centering on electronic circuits are becoming commonsense skills, as well as skills to write emails and watch websites. Based on these backgrounds, this lecture aims at acquiring prototyping literacy through various hands-on workshop practices. Instead of explaining the basic theory of analog / digital circuits, we aim to master basic skills of manufacturing based on electronic circuits.
