From the project
Interactive dual-core RP2040 wand dueling system with on-device TinyML gesture recognition, 38 kHz NEC IR combat, 16x16 LED matrix, and custom PCB.
An interactive, dual-wand dueling system built on the Raspberry Pi RP2040 microcontroller. The wand tracks physical spell-casting gestures in real time using on-device machine learning (TinyML), transmits spell data wirelessly over 38 kHz modulated infrared, renders real-time combat status and animations on a 16x16 RGB LED matrix, and delivers tactile feedback via an onboard haptic motor driver.
