Powered Candy Dispenser (with Live Treats!) on Raspberry Pi 5
summary
A complete, working M&Ms dispenser runs a Flutter UI on Raspberry Pi 5 (4 GB) driving a continuous‑rotation servo attached to a 3D‑printed mount; hardware includes a WaveShare touchscreen, a Bamboo A1S print, and a PCA9685 servo controller over I²C. Development uses a snap/popdev bootstrap that registers the Pi as a remote debug target, favors D‑Bus + Python driver to call existing Python PCA9685 code from Dart, and the live demo functions though one display suffered transport damage.
