- INA219 breakout, i2c
- 16x2 LCD, i2c
- 2 buttons
- controlled by attiny85
Uses PlatformIO as build platform.
- Uses TinyWire as i2c implementation. There are modified libraries for INA219 and LCD communicatin included in the repository since they had to be modified in order to work with TinyWire.
