#Makevember Post 06 – K9’s Back!

I missed a Makevember post yesterday, and the one for today is going to be quite virtual again…

Last time I did a post on K-9’s Back it was to work out how to read the buttons, and to do a first draft of the CADing up for the 3D Printed plastic part, This time its for the LEDs:

Colours of the buttons
Charlieplexing of 12 leds

The 12 LEDs are ‘Charliplexed’ so they only require 4 output lines on a micro controller.
