Description
Here's an idea to implement a luminostat. White LEDs leak into the IR range, so our IR PDs can detect them. We can use this signal to change the LED % to keep a near-constant signal from our PDs.
Given target luminosity L, and initial intensity P
every N minutes:
1. Turn on white LEDs to percent P
2. use ADCReader to measure the exposed PDs signal, l
3. Increase or decrease P s.t. l=L

Research direction
Start by locating the ADCReader entry point and the existing white-LED and exposed-photodiode control code. Use the proposed target luminosity L, initial intensity P, and N-minute loop as the behavioral requirements. Done means the white LED intensity adjusts based on the measured photodiode signal to maintain the target.
