// constants won't change. They're used here to // set pin numbers: const int buttonPin1 = 2; // the number of the pushbutton pin const int buttonPin2 = 3; // the number of the pushbutton pin const int buttonPin3 = 4; // the number of the pushbutton pin const int speakerPin = 11; //the number of […]
Read More →/* Analog Input Demonstrates analog input by reading an analog sensor on analog pin 0 and turning on and off a light emitting diode(LED) connected to digital pin 13. The amount of time the LED will be on and off depends on the value obtained by analogRead(). The circuit: * Potentiometer attached to analog input […]
Read More →/* Blink Turns on an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the Uno and Leonardo, it is attached to digital pin 13. If you're unsure what pin the on-board LED is connected to on your Arduino model, check the documentation […]
