## Article

This is a wireless tally lighting control board production project spanning a total of 5 postings.

> Tally light is a small signal-lamp on a professional video camera or monitor. It is usually located just above the lens or on the electronic viewfinder and communicates, for the benefit of those in front of the camera as well we the camera operator, that the camera is 'live' - i.e. its signal is being used for the 'main program' at that moment
> (by WIKIPEDIA, <https://en.wikipedia.org/wiki/Tally_light>)

Tally Controller is connected to ATEM switcher (Multi camera production switcher). ATEM basically supports wire interfaces to control camera. Tally Controller can extend wireless connection for multi camera devices.
