Bill Earl’s new tutorial on Adafruit is about multitasking with Arduino where he explains practically how to program an Arduino board to perform multiple independent tasks without the processor being tied up to any kind of delay. His approach define each task as an independent state machine which can execute without affecting or being affected by the others.

Audio/video transport controllers are used in recording studios and live performance setups for quick hands-on control on demanding editing or mixing tasks. These devices are an expensive piece of hardware (costs from a few hundreds to thousands of USD). Victor Frost’s OpenTransport project would allow hobbyists to build an external transport control surface at very low price. It is an open-source, open hardware transport controller that sends out MIDI commands and therefore, works with most of the Digital Audio Workstation and Digital Video Workstation softwares. It is Arduino-powered and provides controls for play, stop, fast forward, rewind, record, loop, and mackie keys Function 1 and

I hope all of you had a wonderful and safe Halloween. Ours was great. We had a lot of fun taking out our 3-year old son, who dressed up like Curious George (his favorite cartoon character), for trick or treat in our neighborhood. The most difficult part of Halloween is choosing costumes for kids. We all want to do something different every year. And so did [melarky], who made a pretty neat animated robot mask for his oldest son to wear on Halloween this year. His robot mask uses Adafruit’s neopixel rings for robot eyes, an old iPhone running MouthOff app for its

In Part 1 of this project, we described the construction of Easy Matrix, which is a cascadable 8×8 LED matrix display with MAX7219 chip on board. We developed an Arduino sketch for scrolling text display, whereby the Arduino receives text messages from its serial port and displays the message on a 8×40 LED matrix constructed by daisy-chaining five Easy Matrix modules. The Arduino firmware is also capable of receiving user commands for controlling the scrolling speed and brightness level of the display. In this part, we will discuss about extending the project to cascade 8 Easy Matrix modules and control

LED matrix displays are great fun. They are visually charming, and readable from a far viewing distance with a much wider angle of view as compared to many other types of electronics displays. They can display all kinds of information, including text, graphics, and animation. This project is about making a portable Bluetooth-controlled 8×64 monochromatic LED matrix (total 512 LEDs) for displaying scrolling text message. I made this display to use at home parties or other occasions for displaying greeting messages. The text data to be displayed can be sent from a smartphone using the Bluetooth connection. The display is Arduino-controlled and uses the
