Arduino Attiny Programming Shield
An Attiny is a great alternative to the atmega328, it is for those projects that need few GPIO pins and need to be portable. But unlike the atmgea328 the attiny cannot plug into an Arduino board and be programmed. Another way would be to use a breadboard and an Arduino uno as ISP, but it would be really messy and it would be hard to program it this way multiple times. A better way would be to program it on a shield and in today's instructable I'm going to show you how to build an attiny prog...
SquareWear - open-source microcontroller board. "SquareWear is primarily used for wearable electronics projects, such as reading sensors, controlling LEDs sewed onto fabrics, and sending data to a computer through its USB port. It is low-cost and particularly suitable for beginners of wearable electronic projects or school workshops." Cool!
