![]() The software ended up being pretty simple in the end, but it took a lot of trial and error to get there. With QLab 5 you can do something similar to this, with OSC, by sending your full stage out only to a. I won't dive into how the light strip, mainly because I'm not sure what I'm doing with it yet, but I'm using a spare WS2812B strip that I had to test, connected to a digital pin on the Arduino. You can send UDP commands to QLab from an Arduino. ![]() An Arduino Uno with ethernet shield and a Macbook Pro are both connected by cat5 cable to LAN ports on an old router, set up with static IPs. I chose ethernet rather than DMX because I wanted to keep this separate from lighting control in case of failure (ie the DMX shield on the Arduino fails and kills the DMX chain) and we have a spare ethernet line going from the booth to backstage. My goal was to allow lighting built into set pieces to be controlled from the booth. It took a while to get this working, and this has been discussed in this sub before, so I wanted to share what I did in case it helps anyone. Had a big breakthrough last night with getting an Arduino to successfully receive OSC commands over ethernet from QLab, to control addressable LED strip in a couple big set pieces.

The production was due to be performed in rep at times over a five year period, so I incorporated IP addressing with hexadecimal dip switches and used widely available Cat5e cable to connect everything together. The story needed the lift to be able to go between floor “-99” and the ground floor, so I put together a modular system based around an Arduino, again listening to OSC commands from QLab and driving the displays over serial. While working on “Schatten” as rehearsal lighting programmer, I built a system of dot matrix displays for an onstage lift to replace the displays that came with the set. “Schatten (Eurydike Sagt)” (Schaubühne Berlin) – Lift Displays I'm using the following libraries acquired from Arduino site and from CNMAT for the OSC stuff: SPI.h ethernet2.h ethernetUdp2.h OSCBundle.h I've had some fairly good results so far, but I'm getting stuck at formulating an OSC message which carries a value attached in a way that is accepted by Qlab. The video below shows the clock in action. I also added a couple of Hall effect sensors behind the face to keep track of the minute and hour hands, both with small magnets on the ends. I settled on a small, high resolution stepper motor attached to the existing mechanism part-way through the drive chain, with an Arduino controlling it while taking OSC commands from QLab. I was approached at the start of May to find a way of automating the clock to start running after the opening number and to fast forward to the next “morning” during the penultimate number. In previous productions, a large clock with a conventional mechanical module was used. “Departures: A Song Cycle” performed its fourth iteration of the show at Pleasance Islington in June 2016.
