Popular

So many parts, so many variations, which to pick. Why not try to see what is popular:



If you are working with X then Y

X=PIC's

What Comment Specific Part


The PIC

16F877?


Proto Board

Some People hate them, but many find them a nice quick way to experiment. I have found a max clock speed of 4 megHz works well.

?


Crystals

I keep 4 megHz and 20 meg Hz on hand. Note that some PICs can do without crystals, but timing is not very accurate. Check your spec. sheet, some PICs may be able to go to 40 meg Hz. Note that a couple of capicators are needed as well. Ceramic resinoaters ( sp ) may be used instead.

  • 4 meg Hz
  • 20 meg Hz

Pull Up Resistors

Can be used as pull down. I use 10k ohms, often useful for other stuff as well.

Comment

Voltage Reg

Easy choice is LM7805. A couple of caps usually go with it. .1 and .01 bypass caps are generally useful.

  • 7805
  • .1 uf
  • .01 uf
Op Amp Need to condition you inputs, a op amp may be just the thing, see section on op amps.
