Build a Drum-Style Mechanical Television
Adafruit Blog
EDITOR BRIEF
Scanwheel is a do-it-yourself drum-style mechanical television with five windows that share one scanning drum but use separate LEDs to show different images. Each window is very small and has 20 scan lines, but the Raspberry Pi Pico’s PIO hardware drives the LEDs in a way that gives better horizontal detail than the line count suggests. The software is written in MicroPython.
INSIGHTS
This is a good example of how hardware and software work together to create an image display. If you are learning embedded coding, a useful next step is to study Raspberry Pi Pico PIO and then explore the project on GitHub.
