The project produces a different type of speedometer with separate display and control boards while being built around an AVR ATmega328 microcontroller.
With only few common components, the design of this board is simple while having 3 through-hole connectors dedicated for each MCU pin as the board is used as a fast kick in for MCU starters.
The project is built around a PIC18FL4553 microcontroller that consists of 3 programmable LEDs, reset button, power LED, and various power supply alternatives such as USB/direct 5V or other via voltage regulator.
