16 LED "Heart" 74HC595 board "Newton 10"

February 24th 2016

This kit is a 10mm LED version of the 5mm Newton kit. Watch a video of it in action here.
This board contains two 74HC595 shift registers, which drive 16 10mm LEDs, laid out in a heart-shaped arrangement. Each LED can be controlled individually and will keep its state until changed - so no need to constantly refresh the display, which makes it ideal for slower microcontrollers and multitasking devices like the Raspberry Pi.
This board can be driven by an Arduino, Espruino, PICAXE or Raspberry Pi.
Usage Suggestions
This kit would make a fanastic Valentine's Day project! Alternatively use it as a interestingly shaped binary clock, sound meter, temperature guage...
