Arduino Workshop 2011.05.31

  1. 1. void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait for a second }
  2. 2. void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait for a second }
  3. 3. int brightness = 0; int fadeAmount = 5; void setup() { pinMode(9, OUTPUT); } void loop() { // set the brightness of pin 9: analogWrite(9, brightness); brightness = brightness + fadeAmount; if (brightness == 0 || brightness == 255) { fadeAmount = -fadeAmount ; } delay(30); }
  4. 4. const int buttonPin = 2; const int ledPin = 13; int buttonState = 0; void setup() { pinMode(ledPin, OUTPUT); pinMode(buttonPin, INPUT); } void loop(){ // read the state of the pushbutton value: buttonState = digitalRead(buttonPin); if (buttonState == HIGH) { digitalWrite(ledPin, HIGH); } else { digitalWrite(ledPin, LOW); } }
  5. 5. const int sensorPin = A0; const int ledPin = 9; void setup() { pinMode(ledPin, OUTPUT); } void loop() { // read the value from the sensor: int sensorValue = analogRead(sensorPin); // scale from 0-1023 to 0-255 int intensity = map(sensorValue, 0, 1023, 0, 255); // sets the value analogWrite(ledPin, intensity); }
  6. 6. const int ledPin = 9; void setup() { // initialize the serial communication: Serial.begin(9600); pinMode(ledPin, OUTPUT); } void loop() { byte brightness; // check if data has been sent from the computer: if (Serial.available()) { // read the most recent byte (0-255) brightness = Serial.read(); // set the brightness of the LED: analogWrite(ledPin, brightness); } }
  7. 7. import processing.serial.*; Serial port; void setup() { size(256, 150); // Print available serial ports println(Serial.list()); port = new Serial(this, "COM1", 9600); } void draw() { // draw a gradient from black to white ... // send the current X-position of the mouse port.write(mouseX); }
