> might they be moving too quickly for a break beam IR or photoresistor?
A photocell will respond plenty fast. To get the Arduino to respond quickly enough use a digital photocell or obstacle detector module connected to interrupt-on-change pins, either on Arduino pins directly or via an IO expander like the PCF8575.
I found this 10 pack of light sensors on Amazon: https://www.amazon.com/Gowoops-Digital-Intensity-Detection-Photosensitive/dp/B01N1FKS4L/ref=sr_1_3?keywords=arduino+light+sensor&qid=1565710705&s=gateway&sr=8-3
Let's say I got these and attached them to each LED on the speaker splitter. Would I be able to attach 8 of them (mute LED and 7 zone LEDs) to the same microcontroller?
