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.


/* Serial.print the status of a button and an LED so you can see how the computer 'sees' the component statuses (0 or 1).*/ void setup() { pinMode(3,OUTPUT); //LED light pinMode(12,INPUT_PULLUP); //button will send a LOW (0) signal when pressed Serial.begin(9600); //set the serial port up to receive data } void loop() { digitalWrite(3,digitalRead(12)); //Use the value from the digitalRead of the button as the value for digitalWrite for the LED Serial.print("Button Status: "); //Use serial.print to label the data in the monitor. Serial.println(digitalRead(12)); //Use serial.println to show the data and start a new line in the monitor Serial.print("LED Status: "); //Use serial.print to label the data in the monitor. Serial.println(digitalRead(3)); //Use serial.println to show the data and start a new line in the monitor delay(500); //Delay 500 milliseconds so the data doesn't stream by too fast. //Note that adding a delay will make the button less responsive to your touch. } // (c) 2023 Let's Start Coding.
