MAKE vol 25 features a little article I wrote about building a “Breadboard Arduino”. You can buy a kit that contains all the parts for $40. Click on the giant “Buy Now” button to order one today!
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.
The first 99 buyers also get the “Li’l Larson LED Scanner Expansion Pack”, for free! OK, it’s just 5 red LEDs and some more jumper wires but you do get a really nice, custom laser-cut LED bezel for maximum Cylon (or K.I.T.T.) action!
