Week 8 Recipe: Output Testing

Cooking up sound with circuits

Serves: One electronics chef with a ready-to-play PCB

Course 1: Preparing the Dish

For output testing, I reused the code from Week 7 and the PCB designed in Week 4. I attached a speaker to the board and prepared WAV files from audio.com for fast and slow tempo examples.

Course 2: Serving the Output

The code worked perfectly! The accelerometer input now controls audio output, demonstrating the full signal chain from input to sound.
