Car trip computer

Small but "powerful" Arduino-based car trip computer, with OLED display. It counts fuel usage, remaining fuel, remaining range, average speed, distance, internal/extarnal temperature and even time for 1/4 mile drag race :) Everything fits into place after original clock. It works on "low-level" signals from injectors, speed sensor, without OBD.

Partially based on concept & code from: https://github.com/xtensa/xarias
