Using the Arduino Uno as a Tally controller for the Panasonic AG-HMX100 Mixer

Projects General Guidance

Hello All :smiley:

Me and a fellow AV helper were discussing the use of Tally lights for school productions (namely graduation). Unfortunately, the price of a Tally system is too deep for our pockets, so he came up with the idea that you could use an Arduino board as one. It seems simple enough, and apparently, it's been done before, but for other mixers and boards. I'm a novice programer, so I'd like some help making this happen. Weather it's guiding me through how to do it, or just clapping some code in and saying "here you go, go to town," any and all help is appreciated. :slight_smile:

Hi,

In think you don't need an Arduino to make tally lights.

You switcher is equiped with open collector inputs to switch your tally lights.

See http://www.panasonic.com/business/provideo/includes/pdf/AG-HMX100_OIAdvanced.pdf on page 29

The only thing you need are tally lights eg: Datavideo | Professional end-to-end solutions provider for your live video production.
A small powersupply and a resistor/ tally to terminate the current drown by tally. You can see an example in the instruction manual of the TD2 page 6 http://www.resource.datavideo.info/manuals/Datavideo_TD-2.pdf

Kind regards
