Sync Rising Brightness and Tone

// Brighten a color of the jumbo LED as the tones on the speaker rise void setup(){ pinMode(9,OUTPUT); //Color 9 of the jumbo multicolor LED pinMode(A5,OUTPUT); //Speaker } void loop(){ analogWrite(9,50); //Set pin to a brightness of 50. analogWrite range is 0 - 255 tone(A5,50); //Play a tone of 50 hertz on speaker pin (A5) delay(500); //Wait 500 milliseconds (1/2 second) analogWrite(9,150); //Set pin 9 to a brightness of 150 tone(A5,150); //Play a tone of 150 delay(500); analogWrite(9,250); //Set pin 9 to 250 tone(A5,250); //Play a tone of 250 delay(500); } // (c) 2024 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!

Challenges

Can you complete the challenges? 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!

Add more analogWrite and tone functions to make the fade smoother. Try to get to at least 6 different "phases" of the fade.

Rearrange the functions so that the LED fades from bright to dim each time the loop runs.

Can you add another LED color to this program? Don't forget the pinMode function!
