Interactive Experiences Using Flutter, Arduino, Raspberry Pi
summary
Shows hardware projects that actually run: Decisionator and Flip Puck run on a Raspberry Pi 4B (8GB) with the Flame engine and Flutterpie, a Big Blue Button uses an Arduino Nano over USB sending "activate"/"deactivate" to control LED strips, and 20 generated fortunes play correctly. Serial communication uses libserialport; analog input from a potentiometer maps 0–1023 to 0–100 and is smoothed with a 10-sample moving average. GPIO access on Pi uses flutter_gpiod and Buildroot is recommended for minimal Linux builds.
