Arduino^

A open source microcontroller platform, featuring very easy to use hardware and software based on the Atmel AVR processor, USB interface to a host PC, and a simple, C based Integrated Development Environment. The IDE has been adapted for use with MANY processors and devices, includeing the ESP-8266

Intefacing to the LCD Panel 1 by Bud Justen

The BOB Panel adds LCD, LEDs, Switchs, relay driver, or breakout to full sized stepper motor drivers.

When using the Tinyduino or other Pro / Mini versions, make sure the correct processor speed is set. The processor selection option only appears under the tool menu after the board is selected. If you have the Tinyduino set to the 5 volt / 16MHz Atmega 328, it will return garbage on the serial port. Use the Atmega 328 (3.3v, 8MHz) option for correct operation.

The Node.JS code could be moved out onto an embedded device or a dedicated PC server.
