Christmas lights

A very quick hack as julpyssel. Source code available for two implementions Arduino code and rust version for digispark at85tiny

• Get a few battery powered christmas leds in Akihabara
• Measure current and find it was low enough to be driven by a gpio
• Ad a arduino from the project.
• PWM on a few ports.
• A few years later deploy a new batch with the ATtiny85 digispark arduino platform and reimplement in Rust
