Jitter the Motor and Beep in Sync

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.


// Beep a speaker in sync with a jitter on Buzz's motor and a blink of his eye void setup(){ pinMode(9,OUTPUT); //Motor pinMode(2,OUTPUT); //Speaker pinMode(4,OUTPUT); //LED } void loop(){ digitalWrite(9,HIGH); //Turn on the motor digitalWrite(4,HIGH); //Turn on the LED tone(2,550); // Play a tone of 250 hertz on speaker pin (2) delay(1000); //Wait 1000 milliseconds (one second) with the light & motor on digitalWrite(9,LOW); //Turn off the motor digitalWrite(4,LOW); //Turn off the LED noTone(2); //Turn off the tone playing on the speaker delay(1000); //Wait 1000 milliseconds before restarting the loop } //(c) 2023 Let's Start Coding.
