About Me

  • BS in Computer Engineering from UCF
  • Background in Web Development
  • Working at the Center for Distributed Learning at UCF as Techrangers Team Lead

What is Arduino?

  • Small, cheap, low-power computer
  • Interact with and react to the world

Input

  • Can receive/record input through sensors
    • Temperature
    • Light
    • Humidity
    • Air Pressure
    • Distance
    • Movement
    • GPS

Output

  • Display Things
    • Signs
    • LED Arrays
  • Control things
    • Lights
    • Motors
    • Relays

Buying an Arduino

Before you buy:
Have a project in mind.

Arduino Vs. Compatibles

Official Arduinos are made by Arduino.cc in Italy.
Arduino Logo

Guaranteed to work with the Arduino software.

Arduino Vs. Compatibles

"Arduino-Compatible" boards work with the Arduino software, but might need special drivers or have other requirements. (Most are fine, though.)

Some Manufacturers:
Sparkfun ElectronicsSeeed Studio
Adafruit IndustriesPJRC

Formats


Arduino LeonardoArduino Po Mini
LilyPadArduino Mega

Arduino Leonardo

  • Latest and Greatest
  • Uses microUSB instead of USB B
  • $20-25
Arduino Leonardo

Supplemental Equipment

Micro USB Cable

Probably the same as your cell phone charger.

Starter Kit

  • Starter Kit
    • Prototype Board, Jumpers, Resistors, LEDs
    • $23

Power Adapter

  • Optional
    • Only needed when away from a computer
  • 9-12V, 250mA or more
  • 2.1mm Jack, Positive Center
  • http://goo.gl/8N2pD ($8)

It Arrived!  What Now?

  • Install software 
  • Connect the Arduino
  • Run the software
  • Select the correct board (Tools -> Board)
  • Select the correct serial port (Tools -> Serial Port)

Tools > Board > Arduino LeonardoTools > Select Board > tty-usbmodemfd121

Running your First Program

  • Go to File > Examples > 01.Basic > Blink
  • Turns the amber LED on for one second then off for one second.
  • You can make sure the board is working.
  • You can start experimenting with timing.

Anatomy of an Arduino Program

// Pin 13 has an LED connected on most Arduino boards. // give it a name: int led = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }

Essentials

  • Define global variables and constants at the top
  • The Setup function is for initializing pins and devices
  • The Loop function runs over and over as fast as it can
    • Put a delay at the end to slow it down.
