16 LED, 4x4 Grid 74HC595 board "Orion 4x4"

February 24th 2016

A complete kit for building a shift register powered 4x4 LED grid. Works with many different microcontroller platforms (PIC, Picaxe, Arduino, Raspberry Pi and Parallax).
The first image (below) shows the board standing up using the included 18mm hex spacers and screws.
It's not a difficult or intricate project, and can be soldered by a beginner in less than 30 minutes. It comes with all the parts above to build a shift register controlled 16 LED 4x4 grid. Each LED is connected to one of the shift register outputs meaning there is no need to constantly refresh the display - once the LEDs are on/off they stay that way!
This board can be driven by an Arduino, PICAXE, Parallax, or Raspberry Pi.
Usage Suggestions
Make it flash in random for an 80's sci-fi computer type effect (code included), use it as a debug output, strangely-shaped sensor feedback, clock... and many more besides. Scroll messages across it, or show the temperature.
Have a look at the example code, and YouTube videos, for inspiration.
Stands up using the included hex spacers and screws, ideal for sitting on your desk.

  Example code for Arduino, PICAXE microcontrollers and the Raspberry Pi.   Several examples that you can use as the basis for bigger and better projects.
