7 Segment with Backpack - Not Working Past 1st Run

Post by malcolmlangille »

We are experiencing random failures with our Arduino Uno with 2 7 Segment Displays with backpacks each.

A typical scenario starts with:

(1) Turn the arduino on and get the word "Play".

(2) We initiate a count down from 30 seconds with a a button.

(3) Count down occurs but the 7 segment goes off completely at various intervals or the 7 segments don't turn on after two cycles, etc, etc.

Basically a lot of random failing. (Sometimes one 7 segment works while the other doesn't.)

Any ideas? Thanks!
