Random Beep Delays

Code

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.


/* Beep the speaker with random delays between the beeps */ void setup(){ pinMode(A5,OUTPUT); //speaker } void loop(){ tone(A5,500); //start playing a tone of 500 hertz on the speaker delay(random(10,2000)); // delay between 10 and 1999 milliseconds (0.01 to almost 2 seconds) noTone(A5); //stop the tone delay(random(10,2000)); //delay between 10 and 1999 milliseconds before starting the loop again //Note: each time 'random()' runs, it selects a new number, so every loop will be different! } // (c) 2021 Let's Start Coding.
