Hi All,

this is probably something simple but I can't seem to get it to work correctly. I am using an Arduino Uno to drive the tally on my LCD viewfinders. When the input it on program I can get the red tally on and preview the green tally - that part works fine. The issue I am having is when the input is not on preview or program the red tally lights up again. Has anyone used the Uno for tally and run into this problem?

Thanks for any help

Curtis

I'll take a wild guess, try connecting a 10K resistor from the pin to +5v or ground.
The pins may be in tristate mode.
