What's all this "PICAXE" Stuff ??

    PICAXE microcontrollers are exciting, low-cost, re-programmable chips that can be used as low-cost 'brains' in many kinds of electronic project.  Microcontrollers are exciting new electronic ‘single chip computers’ that are rapidly being introduced into industry and education. The ‘PICAXE’ system is an extremely powerful, yet low cost, microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers. The unique feature of the PICAXE system is that programs are downloaded via a direct cable link straight into the microcontroller, so no expensive programmers or erasers are required. The easy to use software is free, and so this low cost approach also means that students can use the whole programming system at home.  Similar to the Parallax Basic Stamp microcontroller, the PICAXE differs in that it is a self contained controller (i.e. does not use an external EEPROM like the Stamp controllers).  Additionally, the PICAXE incorporates an internal resonator/crystal, buried deep inside the PIC.  Although you are programming a PIC, you are programming it in a "BASIC" like language that is very easy to learn.  Revolution Education (aka RevEd) located in the United Kingdom is the manufacturer of the PICAXE.  I purchase my PICAXEs through my ever faithful & trusty professor, Peter H. Anderson of Morgan State University. Another viable source is ???

The PICAXE microcontrollers are available in four sizes:

	The 8 pin version provides 5 i/o pins (1 analogue input).
	The 18 pin version provides 8 outputs and 5 inputs (3 of the inputs have analogue capabilities).
	The 28-pin version provides 9-17 outputs, 0-12 inputs and 0-4 separate analogue inputs.
	The 40-pin version provides 9-17 outputs, 8-20 inputs and 3-7 separate analogue inputs.
