    Controlling LEDs with Arduino(adapted from a document by Victor Gallego)

    Practice 1: Blinking LED

    We need:1 protoboard1 LED1 resistor of 220Ωwires

    Circuit:

    Program:

    // Project 1 – Blinking LED int ledPin = 10;

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

    void loop() { digitalWrite(ledPin, HIGH); delay(1000); digitalWrite(ledPin, LOW); delay(1000);

    }

    Exercises:1.1. Put comments in every line in the program1.2. Change the time of blinking

    Practice 2: Morse S.O.S.

    We need:The same circuit as in practice 1.

    Program:

    int ledPin = 10;

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

    void loop(){ for (int x=0; x

    delay(100); } delay(5000);}

    Ejercicios:2.1 Put comments in every line in the program2.2 Search in the Internet the Morse code for your name. Change the program so it transmits your name.

    Practice 3: Traffic lights

    We need:1 protoboard1 yellow LED1 red LED1 green LED3 resistors of 220Ω

    Circuit:

    Programa:

  • IES Gómez-Moreno Departamento de Tecnología

    // Practice 3 – Traffic lightsint ledDelay = 10000; int redPin = 10;int yellowPin = 9;int greenPin = 8;

    void setup() { pinMode(redPin, OUTPUT); pinMode(yellowPin, OUTPUT); pinMode(greenPin, OUTPUT);}

    void loop() { digitalWrite(redPin, HIGH); delay(ledDelay); digitalWrite(yellowPin, HIGH); delay(2000); digitalWrite(greenPin, HIGH); digitalWrite(redPin, LOW); digitalWrite(yellowPin, LOW); delay(ledDelay); digitalWrite(yellowPin, HIGH); digitalWrite(greenPin, LOW); delay(2000); digitalWrite(yellowPin, LOW); }

    Practice 4: Interactive traffic lights

    We need:1 protoboard1 yellow LED2 red LEDs2 green LEDs5 resistors of 220Ω1 PTM switch1 pull-down resistor
