Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

Description

You will squeak with delight when you hold this adorable miniature LED matrix. 0.8″ square, its got everything a big LED matrix has, but bite-sized! 64 bright white LEDs are contained inside the plastic body, in an 8×8 matrix. There are 16 pins on the side, 8 on each, with 0.1″ spacing so you can easily plug it into a breadboard with plenty of space to wire it up

Since the display is in a grid, you’ll need to 1:8 multiplex control it. We suggest either using a 74HC595 and TPIC6B595 (using the 74HC’ to control the 8 anodes at once and then using the TPIC’ to drive one cathode at a time) or just using a single MAX7219 which will do the multiplexing work for you.

The Arduino playground has a nice set of tutorials introducing the MAX7219 and 8×8 LED matrices
