RE: Arduino Input multiplexer

tabarus12 — Sat, 23 Feb 2013 21:09:54 GMT

Here a corrected version of the multiplexer program.

Ive added a correction to the array and a for routine to pront serial data to port. Enjoy[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-7fe7c75b-6768-4929-9ffe-16293669486f/contentimage_5F00_3.png:16:16]
