One randomly drawn winner will be chosen from today's entrants -- contest closes at 11:59pm PDT each day -- to receive Adafruit MetroX Classic Kit - Experimentation Kit for Metro 328. 

Adafruit description:

Interested in making neat stuff with an Arduino-compatible board but not sure where to start? This kit includes all the pieces needed to complete over 20 different circuit and projects. Basically everything you need to be playing within minutes of its arrival. No soldering required, works with Mac, Windows and Linux!

New! As of March 28, 2018 we've done a big refresh on this kit, to add more stuff like a character LCD, Infrared remote and receiver, improved light sensor, and a full online learn guide with many more projects and tutorials! We've also updated it to use the Adafruit Metro 328.

This pack includes the Adafruit Metro. METRO is the culmination of years of playing with AVRs: we wanted to make a development board that is easy to use and is hacker friendly. At the heart is an ATmega328P, with 32KB of flash and 2KB of RAM, running at 16 MHz. It is fully compatible with the Arduino IDE (select "Arduino UNO" in the board-type menu).
