Software control of white LED

Manual transfer of https://github.com/AllenNeuralDynamics/aind-behavior-blog/issues/1360

• Want ability to automatically turn on white LED when there is a need to visualize pupil in behavior videos
• Should add a note to metadata that there is a white LED

Want ability to automatically turn on white LED when there is a need to visualize pupil in behavior videos

This should be easy to add via: https://github.com/AllenNeuralDynamics/harp.device.delux-driver

I would worry a bit about the UI and simply derive the light power from a config file instead of allowing users to tune it. Just to prevent things from drifting across sessions.

If it can be set to a fixed value, that would be wonderful. I have not looked into this myself

If the MVP is that there is value in the rig config, and that gets set at the start of the workflow, that is very easy from a harp/workflow change. As a bonus it gets logged for free too, so you will be able to know what power was used in each session if you ever need it.
