I started with an off-the-shelf ON AIR sign, that just plugs into a 12V power supply |
|
|
If you open up the sign you'll see a little holder for two lamps, it's pretty basic! |
|
|
I removed the lamps |
|
|
And cut some RGBW NeoPixel strip I had handy |
|
|
I decided to go with two strips of 30 LED/meter |
|
|
Some thin wires connect the two strips |
|
|
Some foam tape or packing tape can be used to keep the strips in place. Solder the strip wires to the Feather, the Power pin goes to USB, Ground to Ground, and Data to #12 |
|
|
I plugged in a USB wall adapter with a MicroUSB plug to power it. You can also go with a long USB cable, that way you could plug it into a USB port and also reprogram it when necessary |
|
|
Plug it in and rock out! |
The final code will turn on the NeoPixel RGBW's dimly when powered up and bright red if the stream is detected. You may need to change the NeoPixel definition to RGB instead of RGBW if you're using plain NeoPixels
