Arduino Test

Arduino Test

I made a simple circuit (one wire, one resistor, one Light-dependent resistor) and attached it to my arduino then used the arduino to read values corresponding with how bright it was.

To verify it was working, I had it just send the values back to the computer. The arduino IDE has a serial monitor so you can see what it’s writing. Unfortunately, I don’t know what one can do with data from the serial monitor. So I wrote a C# application to listen in on the virtual serial port the arduino uses and show the data. But that’s nto very interesting, so I grabbed NPlot and figured out how to use it, and made it graph the "light values" over time. 🙂 It graphs in realtime 🙂
