16 LED 74HC595 board "Freeman"

February 24th 2016

 
Overview
 
A 10mm version of this kit is available here. Click here to see a video demo of this kit being used as a binary clock, and driven by a Raspberry Pi.
 
This board can be driven by an Arduino, Espruino, PICAXE, Parallax, or Raspberry Pi.
 
Details
 
This board contains two 74HC595 shift registers which drive 16 LEDs. Each LED can be controlled individually and will keep its state until changed - so no need to constantly refresh the display.
 
Usage Suggestions
 
This board has many uses, it's linear configuration makes it ideal for visually representing the value of a sensor (such as a temperature IC like the DS18B20). It could also be used to illuminate your desk (stick it under your monitor), or as a binary clock/counter.
