The photo resistor values are logged using the "Universal Input"
command from the "Inputs, Outputs" block. In the context menu change
change the display to "LED". This command follows the command
"Arithmetic Operations" from the "Operators" block
8.8.1. Dock the variable output on input "B". Dock the command
"Constant" on input "A". Assign it a value of "15,000" (max. photo
resistor input value). The output value is the difference of "A – B". This
value is forwarded to the command "Calculate with decimal numbers"
from the "Operators" block
command "Control Field Output" from the "Inputs, Outputs" block

In the "Time and horizontal control" field, change the values
for "Y increments" to 10 and "H and V pixels/increments"
to 100 um. Confirm these entries with OK. Next write the
measuring program.

Then you can test the program. Switch
over to the "Control Field" and start the
program. The readings are now displayed
on the oscilloscope. Change the
brightness by covering the sensor with
your hand. The data changes and the
oscilloscope indicates this graphically.
