What I want to do or know
hi, has anyone tried to connect Desktop Spectrometer to arduino? is there any online documentation on how to do that? and how to feed data to the arduino for further data processing and analyzing? I want to scan different objects and compare the spectral patterns using arduino. thanks
The Public Lab spectrometers rely on cameras to make images of diffraction patterns. So the raw data is a photograph or video frame. Processing the image is done online (Spectral Workbench) or on a PC. An Arduino can control a camera and instruct it to take a photo or save a frame of video. The image would typically be saved to an SD card or sent to a browser or PC.
So the processing and analysis of the spectral image is not done by the spectrometer, and could probably not be done by an Arduino. But an Arduino and TTL camera could replace the camera in a Public Lab spectrometer.

thanks cfastie, I have one more question. I was going through the Spectral Workbench website. I noticed that you can extract cvs file of the plots. now I am thinking of letting Spectral Workbench do the image processing and then take the cvs file and feed it to my arduino for the comparison/data analysis. I was wondering if you have any experience with this? or do you know anybody who has attempted to establish a communication between online Spectral Workbench and arduino (so that Spectral Workbench spits out the cvs data automatically to the arduino)?
