Arduino [ simple input / output microcontroller board system] was born, and rapid prototyping became familiar. Over the past two decades, the prototyping boom has turned into literacy. 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. The aim is not to explain basic analog/digital circuit theory, but to acquire basic manufacturing skills with a focus on electronic circuits.
