Lessons

This section contains introductory reading on technical topics in physical computing. If you learn new material best through reading, you’ll find this section valuable. If you prefer learning new material through video, check out the Video menu. To understand these topics through hands-on exercises, see the Labs.
These notes are divided into several sections:
