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.
Each of your “for” loops will run 50 times, not 15 times as the video says, because you have 50 LED Pixels. The video references an LED strip with 15 pixels on it.
The color value used for your LED pixels is i*6, not i*20 as the video says. Because there are 300 possible color values and 50 pixels, dividing color by 6 spreads the color range evenly across the pixels. The second time your “for” loop runs, it will use a color value of 6. The third time it runs, it will use a value of 12, and so on.
Use this spectrum to estimate the color values you'll need for your 'setPixel' arguments to achieve your favorite color!
