Resources and Going Further
Now that you know what polarity is, and how to identify it, why not check out some of these related tutorials:
- Connector Basics - There are a number of connectors which have polarity of their own. Usually this is a great way to make sure you don't apply power or some other signal backwards.
- Diodes - Our shining example of component polarity. This tutorial goes further in-depth on how diodes work, and what types of diodes are out there.
- LilyPad Design Kit Experiment 1 - Circuits don't just exist on breadboards and circuit boards, you can sew them into shirts and other textiles too! Check out the LilyPad Design Kit tutorials to see how to get started. Knowing polarity will be huge in wiring up those LEDs correctly.
