Code
The code in the editor below is ready to run! Plug your Code Lab in to your computer's USB port with the cable and hit 'Upload Your Code!' to see what it does. Change something in the code, like a delay or pin number. Try to add something new to the program - it's yours to tinker with! You can always press the 'Restore' button to return the code to the working example.
Video Notes for Code Lab Users:
You will use “50” instead of “15” as the first argument in your LEDStrip function.
The second and third arguments of the LEDStrip function (13 and 12) do not need to change. These connections are permanently set on Code Lab.
Your “for” loop will run 50 times, not 15 times, because you have 50 LED pixels on your Code Lab.
Your color variable is i*6 instead of i*20 because there are 300 color possible color values. 300 color values divided by 50 pixels is 6. The video references an LED strip with only 15 pixels, and 300 divided by 15 is 20.
Use this spectrum to estimate the color values you'll need for your 'setPixel' arguments to achieve your favorite color!
