Thank you so much for the videos. I am quite enjoying them.

I have a question on this PWM video. How did you get the values to display the graphs in Excel?

mheidenreich commented 3 years ago

This is just standard graphing in Excel - select two columns and choose an option from the menu.

Sorry, my question was not clear. I am asking about the actual values... how did you get those values? I guess I mean “how did you calculated the values that were used to display the graphs in excel?”

mheidenreich commented 3 years ago

The formula is shown below the graph and also used it in the code.
