Library that implements digitalWrite/Read, but that executes these functions in 2 clock ticks instead of Arduino's 50+ clock ticks. Also allows writing something like "digitalWrite( led1 | led2 | led3, HIGH);", changing 3 AVR pins in 4 cycles.
Using an attiny13 and a hall effect sensor to replace the analog guts of the Roland FD-8 hi-hat pedal.
The smallest possible codebase that delivers clock-tick-correct WS2811 timing from an 8 Mhz AVR. Also available in a version that controls 80+ LEDs from a 64 byte RAM attiny13. See this for an example.
