We use a TSL230R Light-to-Frequency converter chip which senses brightness and outputs a frequency.The Agilent E3640A DC Power Supply supplies a 3.3V to the chip, and the Agilent 34401A DMM reads frequencies. We tested the chip with ambient light and five other colors in a lab. The color filters we used are acrylic color dividers. The frequency for each color is characterized and stored in our Color Calibration subVI. After color calibration, multimeter reading will be compared with the calibrated values in the Color Sensing subVI to determine the color. Apparently, the primary application for the project is a color sensor. Another potential application of our VI's is brightness-to-frequency conversion based on the chip we use.

The front panel, wiring diagram, and vi heirachy are shown below.
