Interact the LED with photo diode

[sujeetajeet]

hi i am new in aurdino
I want to interact the LED with photo diode
I have seen the your code in which LED profile is traingular. and output of photodiode accordingly changes.
In my case. I want LED profile in series of square pulse(step function) and accordingly accordingly output of photodiode should change
My LED profile and photodiode graph like this

Regarding this can i get the aurdino code for this
If possible please reply

And your question is?

How to create the square pulse for the LED. ?
When we place the photodiode in front of LED ,so output of photodiode shown in graph.
We want to see the graph for LED and photodiode in serial plotter same as shown in picture?
