Digital Input/Output

Digital Output

Blinking LED

void setup() {
	pinMode(12, OUTPUT);	// Make pin an output for us
}
void loop() {
	digitalWrite(12, HIGH);	// Set pin to be "+" (on)
	delay(500);
	digitalWrite(12, LOW);	// Set pin to be "-" (off)
	delay(500);
}

Digital Input

Pull a pin "up" (+)

void setup() {
	pinMode(2, INPUT);	// Make pin 2 an input for us
}
void loop() {
	int value = digitalRead(2);	// Read what's on that pin
}

Digital Input

Pull a pin "down" (-)

void setup() {
	pinMode(2, INPUT);	// Make pin 2 an input for us
	digitalWrite(2, HIGH);	// Activate internal pull-up
}
void loop() {
	value = digitalRead(2);	// Read what's on that pin
}

Digital Input

Using a Bread Board

Analog Input/Output

Arduino Analog Input

int potPin = A0;
int val = 0;

void setup() {
	pinMode(ledPin, OUTPUT);
}

void loop() {
	val = analogRead(potPin);
	
	digitalWrite(ledPin, HIGH);
	delay(val);
	digitalWrite(ledPin, LOW);
	delay(val);
}

Analog Output

PWM — Pulse Width Modulation

Analog Output

Analog Output: Servo

  • PWM freq is 50 Hz (i.e. every 20 ms)
  • Pulse width ranges from 1 to 2 ms
  • 1 ms = full anti-clockwise position
  • 2 ms = full clockwise position

Analog Output: Servo

Analog Output: Servo

"Servos, Oida!" ☺

Analog Output: RGB LED
