Today LED (light emitting diodes) is the predominant technology to produce light: it is efficient, LED are physically rugged, cheap to produce, and come in various colors and shapes.
Fundamental LED Types
We all know the classic indicator LED but there are many more LED types.
Check out the LED section to find out about multicolor, programmable, stips, high performance and COB LED.
Supporting Components
To actually (and safely) operate LED in your various scenarios, additional components may be required:
- Power Supply: Constant voltage or better yet constant current
- Breakout Boards: A number of breakout boards exist to help you control multiple LED with just two GPIO, either by using multiplexer or I2C
I’ll add appropriate sub-sections soon.
Comments
Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.
Here is how your comments are stored
Whenever you leave a comment, a new github issue is created on your behalf.
-
All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.
-
There is no third-party provider, no disrupting ads, and everything remains transparent inside github.
Github Users Yes, Spammers No
To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant utteranc.es the permission to submit issues on your behalf.
If you don’t have a github account yet, go get yourself one - it’s free and simple.
If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.
Discussions
For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
