If you are relatively new to the world of programmable microcontrollers, the PICAXE line of processors is the perfect place to start, for three major reasons: 1) PICAXE chips are programmed in BASIC - no need to learn a complicated assembly language. 2) PICAXE processors are surprisingly inexpensive - from less than $4 (yes, $4!) for the amazingly small PICAXE-08M (with five I/O pins) to $10 for the super-powerful PICAXE-40X (with 32 I/O pins). 3) The PICAXE Programming Editor (the software you use to write, develop and download your program to a PICAXE processor) is free! What more could you ask for?
