Hi, I'm a software engineer and have just over 10 years of experience behind me some of it very low level (device driver and control etc). I have just joined the list as I am about to embark on a project using a PIC as the brains behind the thing. I guess you can all see my problem, I do not have very much hardware knowledge. I'm hoping to get a PIC up and running and have it flash some LEDs this weekend and am planning on heading to Radio Shack to pick up components this afternoon. Besides the PIC itself and the components to build a programmer I was wondering if you guys could tell me what other components I should buy while I'm there? What would make up the perfect beginners electronics tool box? Also does anyone have any links where I could get a basic grounding in electronics quickly? ie. I know if I connect an LED to an output on the PIC and to GND without a resistor I will probably burn out the PIC due to excess current, but why? and how do I know how much resitance to put between the LED and GND??
