Components: What They Do & Where To Get Them
Each component is described below. I have listed multiple sources for most
components, but have not actually tried all of them, so best treat the specified part

cheaper there than the other sources, sometimes considerably cheaper. Further
savings are usually possible by ordering parts direct from countries like China.

These capacitors provide power supply decoupling (or bypass). The fast switching in
digital circuits creates spikes on the power supply lines which are suppressed with
decoupling capacitors placed at key points on the circuit board.
