Switching multiple drivers

I have a project that I have stalled on and need help. I want to run at least three separate drivers from one switch, with each driver having its own power source. Just for sale of discussion, let’s say 3 or 4 XPL’s each being driven to a different amount. Do I have to build a battery pack and arduino or some such and program it to operate each led or is there a more simple and smaller option. -Use small words, this electronic stuff is a challenge for my little brain.

Whut kinda driver? If 7135-based, you can wire the enable lines together, and when the “master” is enabled, the “slave” drivers will also respond in kind (including pwm, etc.).

Thanks I’ll take a look at this

Æons ago, someone stacked… think it was multiple minimag heads together, each with their own driver, and used the control from one to control all the others.
