TinyDuino Darkness Gauge

[tamberg]

Hi, made a simple darkness gauge with a TinyDuino, LED shield, Proto2 shield and a LDR.

Here's how it looks

This is cool
Did you use a resistor with the  LDR or was it just directly connected to A3 and ground ?

Thank you for posting this code.  I was going to write similar code to support Charlieplexing using the switch / case statement but I suspect my attempt would have been clumsy.

When using the Charlieplexing library, I do not know how to select a CharlinPin at random, so had to go with not using that library.
