Release Notes for 1.0
The zip archive contains of:
Wiring diagram (compatible for Arduino Uno, Nano, Mega, separate AVR chip AtMega328P)
Source code for the microcontroller (compatible with the same Arduino boards as the schematic), two versions of the source code with and without an external pullup resistor for connecting the inputs.
LCD character display library with I2C converter (I2C ONLY!)
The contents of the /src/ folder must be copied to the location of your Arduino IDE libraries to support the library.
