Following steps should be performed before proceeding with the online experiment:-

1.      1)Go to download page and download labVIEW Run Time engine and install it.

2) After installing the runtime engine start performing the experiment.

3) Select run button from tool bar to start real time experiment.

4) The two X-Y graphs show the I-V characteristics of LED and photodetector(LDR).

5)The Gauges depict the measurement values of the respective DC currents and DC voltages as input Voltage varies.

6)The series of LED's indicates the various intensities of the LED as the current through it increases due to increase in input voltage.

7) Click stop buttons to stop execution.
