I'm currently building my first robot, and I have decided to use a PIC microcontroller. Am I right in thinking that together with the little black chip itself, which only costs a couple of $, I will need to buy a crystal oscillator to provide a clock signal, and voltage regulator, and other things, or are these included within the chip? I already have a voltage regulator for the rest of my circuitry, so could I use that?
I also need to get a programming board, that will program the microcontroller via a cable from a PC, right? I'm interested in building one myself, are there any tutorials on doing this?
