basic electronics question

Atmel AVR microcontrollers are another good choice. I recently abandoned PIC's for them.

As for your question, a simple breadboard, a regulated multiple voltage wall plug, an LM7805 voltage regulator and 2 capacitors will give you a steady 5V supply for your breadboard. Alternatively, leave out the plug and use a 9V battery with same setup.

Most microcontrollers work over different voltage ranges, but need to be programmed at 5V, sometimes higher.

Any other questions, just ask or pm and i'll get you kitted out.

If you go for the PICAXE (BASIC programmed with a simple serial download cable and a couple of resistors) there's really no need for a book. The manuals are pretty good and they're extraordinarily easy to get running. The PICAXE forum (www.picaxeforum.co.uk) is good as well: everyone's very willing to help.

You should really use a 5V regulator rather than a potential divider. This is because if the resistance of the running electronics changes, this affects the voltage supplied to it. Someone mentioned the 78L05, perfectly good up to about 100mA.

Make sure you've got a big (220mF+) cap on the output and a small one (100nF) across the microcontroller's power pins to suppress noise and ripple.

Project of mine using a PICAXE: http://www.hexoc.com/altimeter :cool:
 
as above, I just bought a PICAXE board and have managed to get it at least working quite quickly and when you consider i'm an industrial spark its quite a miracle that I could get something so small, fiddly and alien to me to work :)
