Hoping someone here might be able to point me in the right direction! I'm pretty new to this stuff, but I have an idea to make a homemade spectrometer using a CIS sensor salvaged from a scanner.
The plan is to use some kind of dispersive element in front of the light source, and then read the pixel values back from the array, giving a rough spectrum.
I have the datasheet of the CIS: http://rohmfs.rohm.com/en/products/...ontact_image_sensor/flatbed/lsh3008-ca10a.pdf
So I figure I'll connect a 8MHz crystal oscillator to the CLK pin (pin7). Then I just need to generate a start pulse, which I could do with my Arduino. But I can't figure how I would synchronise them?
I figure for reading the output, I could use my Arduino to read out analog values on the out pin.
As you might have guessed, I'm pretty new to this stuff! Any ideas? Am I going about this the wrong way?
Thanks
