Build your own mini robot with the Arduino 101 board. This smart little 'bot contains a 32-bit Intel Curie module, Bluetooth LE capabilities, and a 6-axis accelerometer/gyro! Drive it with your phone, or turn over the controls to this capable robot's own decision making!!

Color Balancing Video Camera Light feat. DotStars

Sometimes you need warm white, and sometimes you need cool white, so why not have both?

by Timothy Reese

A hurdle with all video lighting is getting the color balance correct. This guide is covers how to construct a LiPoly battery powered camera light fitting hotshoes and tripods, for lighting your subjects and bowls of fruit in any combination of warm and cool light with zero flicker.

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.

Arduino Yun Temboo Twitter Tracker

Check Twitter from your Arduino Yún.

by Vaughn Shinall

This guide will demonstrate how to look up Twitter mentions using Temboo, a service that lets you connect your Arduino project to over 100 different APIs.

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.

LED Lightbox

Build a decorative, programmable LED display pretty enough to hang on a wall!

by Sam Clippinger

If you're looking for a simple beginner project that'll produce something beautiful, this is the guide for you. It needs little more than a razor knife and a hot glue gun to put this one together, and it makes a great gift too!

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.

Sending an SMS with Temboo

Use Temboo to connect your Arduino to the cloud.

by Vaughn Shinall

This guide will show you how to send an SMS from your Arduino board using Temboo, a service that lets you connect your Arduino project to over 100 different APIs.

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.

Set up and Blink - MATLAB and Simulink with Arduino

How to use MATLAB and Simulink to communicate with your Arduino

Step-by-step instructions on how to set up and use MATLAB and Simulink Support Packages to program your Arduino Due to blink an LED.

Memories of an Arduino

How to get the most from your Arduino Memory

As your Arduino projects get more sophisticated, they tend to grow to the point where memory limitations can become a problem. This guide explains the different types of Arduino memory and how to use them most effectively.

Adafruit Proto Shield for Arduino

Arduino Prototyping

This is a design for an open-source prototyping shield for Arduino NG/Diecimila. It has tons of cool features, to make prototyping on your Arduino easy.

Adafruit Arduino Selection Guide

Which Arduino is Right for Me?

This guide explains the differences between the various types of Arduinos and Arduino compatible microcontrollers and helps you to select the one that best fits your needs.

Arduino Lesson 17. Email Sending Movement Detector

Use an Arduino to send an email, whenever movement is detected with a PIR sensor.

In this lesson you will learn how to use a PIR movement detector with an Arduino and to have the Arduino communicate with a Python program running on your computer to send an email whenever movement is detected by the sensor.

Arduino Lesson 0. Getting Started

Learn Arduino, Lesson 0. Getting Started

In this lesson, you will learn how to setup your computer to use Arduino and how to set about the lessons that follow.

All About Arduino Libraries

How to install and use Arduino Libraries

This guide takes you step-by-step through the process of installing Arduino libraries on Windows, Mac OSX and Linux platforms.

Arduino Tips, Tricks, and Techniques

Get the most out of your Arduino

Here is a growing collection of tips, tricks, and techniques for the Arduino.

Arduino Lesson 16. Stepper Motors

Learn Arduino, Lesson 16. Stepper Motors

In this lesson you will learn how to control a stepper motor using your Arduino and the same L293D motor control chip that you used with the DC motor in lesson 15.

Arduino Lesson 15. DC Motor Reversing

Learn Arduino, Lesson 15. DC Motor Reversing

This is Lesson 15 in the Learn Arduino Adafruit series. In this lesson, you will learn how to control both the direction and speed of a small DC motor using an Arduino and the L293 motor driver chip.

Arduino Lesson 14. Servo Motors

Learn Arduino, Lesson 14. Servo Motors

This is Lesson 14 in the Learn Arduino Adafruit series. In this lesson, you will learn how to control a servo motor using an Arduino. Firstly, you will get the servo to sweep back and forth automatically and then you will add a pot to control the position of the servo.
