I thought I would share the tally system I built for a ATEM switchers. I was looking around the Internet for different tally light systems for ATEM and I couldn’t find anything that fit my needs for a reasonable price or that wasn’t based on a Wi-Fi or Bluetooth solution for wireless which in my opinion is unreliable and short range.
The system is based on an Arduino Mega or UNO and Xbee 2.4GHz wireless modules. it Consists of 4 wireless modules and 4 wired modules this gives me a total of 8 camera tally lights. The system also has a small box inside with eight buttons, that I use for a “call button” this flashes the Lights red and green on and off. The code is based on SKAARHOJ Open engineering files.
