12LEDcircle - Click for larger, more detailed image

12 bright blue LEDs in a circle – what would you call it?  I call it the “12 LED circle”, or 12LEDcircle for short.  This small, round PCB (1.25 inches in diameter) holds 12 LEDs, a tiny push button for changing display modes and a pre-programmed microcontroller to sequence the LEDs in a variety of mesmerizing patterns.



Breadboard Arduino

MAKE vol 25 features a little article I wrote about building a “Breadboard Arduino”.  I put together a kit with all the parts you need to build the project in the magazine.   The kit includes everything you need: a solderless breadboard, jumper wires, a pre-programmed ATmega328P with pin label, USB adapter and basic components to perform the basic “software experiments” in the article. You need: a computer with a spare USB port that can run the free Arduino IDE software and a USB A to mini-B cable.
