1A: Getting to know the Arduino


Introduction

Arduino is a microcontroller that is an Open Source electronics platform used for prototyping all sorts of projects. Projects consist of a combination of simple motors, servos, LEDs, resistors, speakers and sensors that perform some function. Arduino allows you to create hardware projects and gives you the ability to create software programs to operate your hardware.

The Arduino ARDX kit from Adafruit (www.adafruit.com) will be used as our electronics platform (Arduino Experimentation Kit)

Definitions

Microcontroller - A small computer that has digital devices or peripherals built in to help control things.

Peripherals - Devices that allow a microcontroller to sense the environment and / or drive the actions of external devices

Examples:

  • mouse
  • keyboard
  • monitor
  • printer
  • temperature sensor
  • photo resister
  • LED
  • push button
  • motor
