/* Button Turns on and off a light emitting diode(LED) connected to digital pin 13, when pressing a pushbutton attached to pin 2. The circuit: * LED attached from pin 13 to ground * pushbutton attached to pin 2 from +3.3V * 10K resistor attached to pin 2 from ground * Note: on most Arduinos there is already an LED on the board attached to pin 13. created 2005 by DojoDave <http://www.0j0.org> modified 30 Aug 2011 by Tom Igoe modified Apr 27 2012 by Robert Wessels This example code is in the public domain. www.arduino.cc/.../Button */ // constants won't change. They're used here to // set pin numbers: const int buttonPin = PUSH2; // the number of the pushbutton pin const int ledPin = GREEN_LED; // the number of the LED pin // variables will change: int buttonState = 0; // variable for reading the pushbutton status void setup() { // initialize the LED pin as an output: pinMode(ledPin, OUTPUT); // initialize the pushbutton pin as an input: pinMode(buttonPin, INPUT_PULLUP); } void loop(){ // read the state of the pushbutton value: buttonState = digitalRead(buttonPin); // check if the pushbutton is pressed. // if it is, the buttonState is HIGH: if (buttonState == HIGH) { // turn LED on: digitalWrite(ledPin, HIGH); } else { // turn LED off: digitalWrite(ledPin, LOW); } }
例如这个按钮例子,只要会Arduino,甚至小白,看看几个例子就会了。
