So on the previous page we integrated, now I want to try and pull off a derivative. This should be relatively simple, here is the circuit:

I used the exact same Arduino code as the previous page. Here is the adjusted data:

You can clearly see that the INPUT is the derivative of the OUTPUT. On the next page I will finally introduce my overall goal and final project: A PID CONTROLLER MADE OF DISCRETE COMPONENTS!
