Mission
-
Connect LED Neopixel - Make sure to wire up your Neopixels correctly. Follow the instructions in the video. If you wire things incorrectly you might damage your Neopixels and they will no longer work! Install the library and play around with the demo sketch.
-
Turn Neopixels On Using Light Sensor - Use the link above to learn how to turn your NeoPixels on or off using the light sensor, similar to what we did with 1 LED light.
-
Add Effects to Your Neopixel - Use the code above to add different effects to your NeoPixels. Remember they will still be turning on or off using the light sensor!
