Hello..I am new on this forum so please don't kill me if this has been covered. I have a large old theater that is being upgraded to DMX controlled house lights. We have a beautiful old control panel that will be kelp for historical purposes. I would like to connect several dry contact switches to some of the old controls to trigger scenes such as house lights and work lights. Hoping someone can help with a solid and reliable yet simple way to make this work. Taking this one step further to include a potentiometer for house light master would be great. In addition I would like to build a custom widget page with just a few scene faders for controlling house lights and work lights. Can this page be full screen and locked? This needs to be idiot proof. Please and Thanks! Jeff

Hi,
- one way is to to use Raspberry PI and its GPIO pins (these are your keywords to search the forum). You can connect the switches directly to the Pi,
for potentiometer you'll need external ADC curcuit; QLC+ on Raspberry has support for gpio.
- another way is to make MIDI controller based on arduino (again, those are your google keywords, there are lots of examples). Most probably you can connect
the switches and potentiometer (almost) directly to arduino, and you can connect the arduino to any computer (using MIDI or USB-MIDI). Example: https://create.arduino.cc/projecthub/Hy ... ler-75ab03 QLC+ has support for MIDI devices (see input profiles in documentation).
For locked full screen, saerch "kiosk mode" and check command line options in the help/documentation.
