The spectrometer was designed to work on a Watterott StarterKit Roboter V2. This spectrophotometer can then be used as an analytical tool for a number of simple chemical reactions, as well as for monitoring simple cell growth, such as with yeast or algae. This tutorial is the second in a series on adding displays to expand the capability of the Arduino data loggers described in our SENSORS paper earlier this year. Audio Spectrum. You could also use an Arduino Uno (which supports only six PWM outputs) if you would be happy combining the left and right channels and losing one of the frequency bands. The audio is picked up with a SparkFun Electret Microphone and then fed into the Spectrum shield. Spectrum Software was founded in February of 1980 to provide software for personal computers. I chose to use a stepper motor because it can be turned in discrete steps. In this tutorial you learn how to use an infrared sensor in combination with the NEC Infrared Transmission Protocol.

Sound is broken down into seven frequency bands and the peak level for each band can be read. Physics, much? Let me make it simple for you. I chose to create a Java GUI using JFreeChart to read the data from the Arduino using an FTDI cable on a serial port (or actually USB) and visualize that in the GUI. To build a spectroscope that produces images that are more easily photographed you’ll need a larger box that can completely enclose the camera and a way to mount the diffraction grating in front of the camera’s lens. In a way, by using the three LEDs we are playing. In this project, we are interfacing UV Sensor ML8511 with Arduino for measuring Ultra Violet Light Intensity in mW/cm^2.
