The Arduino Uno clone "the Shrimp" with LCD display.

Some of the WAX Group members building their own Shrimp.

The Shrimp uses the same CPU (and programming software) as the Arduino Uno (ATMEGA328P)  but costs much less. See https://www.arduino.cc/ for more info about the Arduino and download the latest version of the Arduino IDE for programming at https://www.arduino.cc/en/Main/Software . Adafruit is another good source for information about the Arduino and what you can do with it: https://learn.adafruit.com/category/learn-arduino .
