演示:
int xPin = A1;
int yPin = A0;
int buttonPin = 2;
int xPosition = 0;
int yPosition = 0;
int buttonState = 0;
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
pinMode(xPin, INPUT);
pinMode(yPin, INPUT);
//activate pull-up resistor on the push-button pin
pinMode(buttonPin, INPUT_PULLUP);
// For versions prior to Arduino 1.0.1
// pinMode(buttonPin, INPUT);
// digitalWrite(buttonPin, HIGH);
}
void loop() {
xPosition = analogRead(xPin);
yPosition = analogRead(yPin);
buttonState = digitalRead(buttonPin);
Serial.print("X: ");
Serial.print(xPosition);
Serial.print(" | Y: ");
Serial.print(yPosition);
Serial.print(" | Button: ");
Serial.println(buttonState);
delay(1000); // add some delay between reads
