The course website (linked) contains the documentation and bill of materials for each lab assignment. All lectures will be posted online starting 8/22/2022. We'll be synthesizing cricket chirps, animating flocking algorithms, and balancing an inverted pendulum with a reaction wheel. Please feel free to follow along.
