This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Case in point, Make’s guide to make your gigantic, Jumbotron-esque LED video screen. The project here is powered by a Teensy microcontroller, a bunch of LED strips, and a handful of other parts.

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The Pixel 2.0 has surpassed its goal of $5,000 so it’s ready to ride. This is the second version of the Pixel created by Rabid Prototypes of Boston. They also make a nice high speed Arduino ...

Although there is already an Arduino Wi-Fi shield the WifiDuino device has been designed with a smaller form factor in mind, is more reasonably priced and has been created to be a lot easier to use.

The board also hosts a constant-current LED driver which takes care of the backlight, and allowed him to build in a level converter (since the screen communicates at 3.3V but Arduino uses 5V logic).

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...
