Buzz Motor Strength Fades Up and Down

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.


/* Fade up and down the strength of Buzz's motor*/ void setup(){ pinMode(9,OUTPUT); //motor } void loop(){ /*create a 'counter' variable starting at 0 and, as long as the variable is less than 256, run the code between the curly braces, then increase the value of the 'i' variable by 1 */ for(int i = 1; i < 256; i++){ analogWrite(9,i); //use the value of 'i' to determine the strength of the buzz on the motor delay(10); //wait 10 milliseconds (0.01 seconds) before running the 'for' loop again } /*create a 'counter' variable starting at 255 and, as long as the variable is greater than 0, run the code between the curly braces, then decrease the value of the 'i' variable by 1 */ for(int i = 255; i > 0; i--){ analogWrite(9,i); //use the value of 'i' to determine the strength of the buzz on the motor delay(10); //wait 10 milliseconds (0.01 seconds) before running the 'for' loop again } } // (c) 2023 Let's Start Coding.
