RGBA board for absorbance/fluorescence?

[gendor]

Hi Noah!

A while ago I wrote an experiment profile for the AS7341 spectrometer board to turn the white light LED on that board on and off if that helps:

Normally on spectrometer led

I just wrote an experiment profile to keep it on for 20 hours and then turn off for 4 hours: experiment_profile_name: Spectrometer Daily Cycle metadata: author: Gerrit Niezen description: Cycles the spectrometer on for 20 hours and off for 4 hours to use the light for microalgae growth. common: jobs: spectrometer_reading: actions: - type: start hours_elapsed: 0.0 - type: stop hours_elapsed: 20.0 - type: repeat hours_elapse…

Yes, unfortunately the the IO Rodeo LED boards can’t be controlled automatically. I think IO Rodeo has been working on a version that can be controlled via I2C - I’ll get in touch with them and get back to you.

It would be interesting to see if an RGB board would work for fluorescence, as you usually need very specific wavelengths and/or filters and I’m not sure if they’re bright enough?
