A simple bord computer for scooters
It is arduino based and uses an LCD to display information
- air temperature: Dallas/Maxim DS18B20 1-wire themometer
- oil temperature: TI LM35 analog thermometer
- battery current: Allegro AC709 current sensor
- voltage: on board ADC via voltage divider
- engine revs: via ICP interrupt of the ATmega
The display is ST7565 based but any display supported by U8Glib should more or less plug and play.
