Blink and Beep on the LED Strip

Code

The code in the editor below is ready to run! Plug 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 Buzz's wings on and off while he chirps a tone */ #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 LED wings. These values won't change with Buzz void setup() { pinMode(2,OUTPUT); //Speaker } void loop() { wings.setPixel(wings.All, 50); //use wings.All to set all the pixels one color, then set the color value between 0 and 299 tone(2,500); //Play a tone of 500 hertz wings.draw(); //Send the setPixel values to Buzz's wings delay(1000); //Wait 1000 milliseconds (1 second) with the tone of 500 playing wings.clear(); //Clear all the pixels - make them have no color wings.draw(); //Send the .clear() function to the wings. noTone(2); //Stop the tone delay(1000); //Wait 1000 milliseconds before restarting the loop } //(c)2023 Let's Start Coding.
