This project consisted of replacing an old technology measurement system user interface. The system works well, but the user interface is limited using a LED display, individual LEDs and pushbuttons. The procedures to make changes to the system are cryptic and not user friendly. See below for the new user interface.
The new user interface uses the Arduino Mega 2560 board.
