ATtiny interfacing

AVR ATtiny microcontroller family is a really interesting and compact platform, for this reason I worked to support it in the PJON Arduino compatible implementation and will be soon compatible also for PJON_ASK wireless implementation.

####How to program ATtiny 45/85 You phisically need at least one ATtiny microcontroller, a breadboard, some jumpers and an Arduino duemilanove / Uno used as an Arduino ISP programmer. Follow High-Low Tech tutorial by David Mellis and get the last version of the attiny repository.

####Use PJON with ATtiny45/85 PJON Arduino compatible implementation works smoothly on PIN 2 and 3, using PJON on PIN 1 and 4 leads to low performance or malfunction. The reasons why this happens are still to be cleared with study and experimentation.
