69. Field Guide to Components
Or, how to recognize electronic parts from quite a long
way away. Here's a quick visual reference guide to the major
components used in the Pinscape expansion boards. We'll cover each
category in greater detail in the chapters that follow.
Note that the example photos are just that - examples. All of these
parts come in an almost infinite variety of shapes, sizes, and colors.
These photos should at least look similar to most of the parts used in
the Pinscape projects, but there's a lot of variation even in that
limited scope, so don't worry if you don't see an exact picture of one
of the parts you're using.
| Description | Examples | Schematic symbols |
|---|---|---|
| Resistor
Resistance value in Ohms (Ω)
|
 |
 |
| Capacitor (ceramic disc)
Capacitance value in Farads (F);
ceramic capacitors are unpolarized
|
|
 |
| Capacitor (electrolytic)
Capacitance value in Farads (F);
electrolytic capacitors are polarized
