Using the ticklish code, I was able to read through it and understand it quickly. I was immediately facing the problem of the servo thinking the button was being pressed at all different times. However, I was able to rework it to the sensitivity of my homemade sensor. I then adjusted the sensor reading so that the servo was activated when it did not detect any weight.

I used this to make a (lack of) pressure-activated noisy focus message. When the sensor noticed that my phone was not on it, the servo made loud sounds and moved around a note that told me to focus.
