While many think of Arduino as strictly for hobbyists, its ease of use makes it a great tool for prototyping products for the mass market. The designers of the Fitbit, a device for tracking your level of activity throughout the day, wrote to the Arduino team to tell them that they’ve been doing just that: […]
To teach children about complexity theory, a group from Indiana University created an electronic game called BeeSim using LilyPad Arduinos and XBee radios: During the game children wear a Bee puppet wrist band with embedded electronics to allow for game play. The children have a finite amount of time (45 seconds) to collect and deposit […]
The bells are played by a series of solenoids, which are controlled by an Arduino micro-controller. The notes that you submit are processed on our web servers and then sent to the Arduino, while we load up live video and audio so that you can watch your song play. If there are users ahead of you in line, the queuing system will let you know how long you’ve got before you can watch your song.
In February and March, O’Reilly Media is running two new online classes with instructor Joseph Gray. The classes are free to attend if you’re watching them online live, and they will be available for sale after the classes are over.
engineerzero was kind enough to give a guided tour of a ginormous Arduino Uno to a handful of faceless Google SketchUp denizens recently. Highlights of the tour included a short stroll down Power Street to Analog Alley, where many different kinds of sensors can be connected. The group also had the incredible opportunity to see […]
Use an Arduino microcontroller to sense invisible electromagnetic fields using wire, a resistor, and an LED.
If you’re an aspiring Alex Trebek with some Arduino skills, you should check out RoysterBot’s Instructable on how to make a Quiz-O-Tron 3000, an electronic quiz contestant lockout system, which allows contestants to “buzz in” during trivia games. He used it at a holiday party and therefore needed something sturdy enough to withstand the hand […]
