Ladyada's Learn Arduino - Lesson #2

Venture deep into the Blink sketch...

OK you've gotten your Arduino set up and also figured out how to use the software to send sketches to the board. Powerful stuff! But...just running example sketches is a little boring. What we really want to do is use our own creativity and skill to write new sketches! That's what we'll be doing in this lesson. To start we will venture deep into the Blink sketch, looking at each line and trying to understand what its doing. Then we will start hacking the sketch, and maybe even meet an internationally-famous DJ and design custom hardware for him!

Ladyada's Learn Arduino - Lesson #1

Hello, World! I am an Arduino and I am here to BLINK!

Ah yes, it is finally time to make your Arduino do something! We're going to start with the classic hello world! of electronics, a blinking light. OK it doesn't sound too exciting, heck you can just flip your desk lamp on and off without needing a microcontroller.. but I promise you, you'll learn a lot!

Ladyada's Learn Arduino - Lesson #0

If you're here, it's because you want to learn how to build and make stuff with electronics! And, you're in luck: there's never been a better time.

Adding Custom Boards to the Arduino v1.6.3 Board Manager

Easily add one click install support for new boards to your copy of the Arduino v1.6.3 IDE!

by Justin Cooper

Multi-tasking the Arduino - Part 3

Unleashing the power of the NeoPixel!

Digital RGB LEDs like the Neopixel are greatfor creating awesome lighting effects. But keeping them responsive to user inputs at the same time can be challenging. And what if you want to have different parts of your project animated in different ways? In this guide, we'll explore techniques to make your pixel patterns lively, flexible and responsive.

Multi-tasking the Arduino - Part 2

Excuse me while I interrupt myself...

Explore the magic of interrupts. Learn how to harness timer interrupts to keep your tasks running like clockwork. And use external and pin-change interrupts to notify you of events that need urgent attention.

Multi-tasking the Arduino - Part 1

Make your Arduino walk and chew gum at the same time.

Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.

Wireless Game Show Poppers for the Classroom!

Pro Trinket + Hacked Duo Pop Game = Game Show Fun!

Ever wanted to create your own game show environment. Hack a Duo Pop Game infrared (IR) receiver so you can create your own game show system using wireless poppers with a PC or Mac computer. This modification allows the IR receiver to interface with both PC and Mac game show software via the USB. This project leverages lessons learned from previous tutorials at adafruit.com involving 1) IR decoding and 2) the virtual USB library. This is a great weekend project for learning about wireless IR protocols and USB communication using the Pro Trinket.
