SpectrometryTechnologyElectrical SchematicPractical RealizationArduino LibraryDirect Management by PCConclusionIn order to build a spectrometer, we need something to illuminate the object under analysis, and something capable of catching the reflected light from the object. It''s not mandatory to have a collimated ray of light, like a laser, but a normal beam works fine, even with a certain angular opening. Producing this kind of light is easy enough: a LEDSee more on open-electronics ANSYS Optics
