Blink Buzz's Wings

Code

The code in the editor below is ready to run! Plug your Buzz 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.

/* Blink all of Buzz's wing pixels on and off once per second */ #include "LEDStrip.h" //The LEDStrip.h library gives your code access to special functions exclusive to the LED Strip LEDStrip wings = LEDStrip(16, A4, A5); //Set up the wings by defining how many pixels (15) and where the wires are connected (green = 13, blue = 12) void setup() {} void loop() { wings.setPixel(wings.All, 200); //use wings.All in the place where the pixel number normally goes,then the color (0-300) wings.draw(); //Send the setPixel values to the wings delay(1000); //Wait 1000 milliseconds (1 second) with the wings lit up wings.clear(); //wings.clear() sets the entire strip have no color value (turned off) wings.draw(); //Send the wings.clear() values to Buzz's wings delay(1000); //Wait 1000 milliseconds before starting the loop again } // (c) 2023 Let's Start Coding.

Walkthrough Video

Watch the video for a line-by-line explanation of how the example program works. Then you'll be ready to make some changes of your own!

Buzz’s LED Pixel Color Spectrum

Use this spectrum to estimate the color values you'll need for your 'setPixel' arguments to achieve your favorite color!

Challenges

Can you complete the challenge? Change the code in your code editor above. Upload your code to see the effect when you're finished. Complete a challenge? Check it off the list!

Change the delay to make the LED pixels blink faster or slower.

Change the color of the entire LED wingspan using the setPixel( ) function.

Blink a single pixel on the wingspan. Hint: You'll need to change 'wings.All' to a pixel number.
