Chapter 4: Color Mixing Lamp

Rust project for the Arduino Uno with phototransistor inputs.

I needed to place the phototransistors more apart than in the chapter blueprint. This created the space to be able to use the color filters.

Normally I don't like leaving commented out code in the repo... maybe the path of my stumble to get the exercise working is better documented with the commented out println.

Build Instructions

  1. Install prerequisites as described in the avr-hal README (avr-gcc, avr-libc, avrdude, ravedude).

  2. Run cargo build to build the firmware.

  3. Run cargo run to flash the firmware to a connected board. If ravedude fails to detect your board, check its documentation at https://crates.io/crates/ravedude.

  4. ravedude will open a console session after flashing where you can interact with the UART console of your board.
