Light Capture - SB
This program captures and stores data from resistor A of a Picoboard. It has to be downloaded to work. To measure light levels, just attach a photoresistor (Radioshack) to jack A of the Picoboard. It was developed to capture color changes in the Briggs-Rauscher reaction for a science fair project.
Down button sends reset signal, moving point to origin and erasing old data. Green flag starts graphing and data collection. The light level is set to "100-resistance" so that it goes up in increased light as the resistance goes down. I did not use light sensor on the board since the photoresistor is part of a separate device. It also allows for 3 more light sensors to be added since the board has four resistance inputs. The data can be copied into a graphing application by right clicking on the data boxes (Light Level and Timer) and exporting data as text.
