Can you help me with a light sensor?

[Miriam13]

I need to make a light sensor  using labview and Arduino ,

as I can do to make it graph

[danielbellorome]

Podrías usar un LDR, con su arreglo correspondiente, y leer las variaciones a través de uno de los puertos análogos de tu Arduino. Después envías las lecturas a LabView y las graficas . Saludos.

You could use a LDR and read the meassures using the Arduino's analog port. Then, send the data to LabView to graph the values.

Here is a link to web page showing how to measure light levels using  a LDR.

For this measurement use LINX.  The LINX example "Analog Read Example (serial Interface)" will plot its input signal as a function of time.

use a photocell and try using a resistor to control the voltage. then use the anolog read values to make an array and the draw the graph using graph function.

good luck.
