Thank you VERY much for your help, you both provided key insights. I am using the slide dimmer + number bit on A0, and that seem to be what is throwing the servo for a loop.
I am trying to make a flux capacitor so that when the number bit shows 88 it would flash a light and flip the servo, which would then send a hot wheels delorian down a ramp.
I added a usb power bit to another input and then I have battery bit -> side dimmer -> number bit ->a0.
Much to my thrill, when that baby hit 88 miles per hour, the servo flipped as expected.
Now that the hardware and software is set, I just need to figure out how to attach the servo to my ramp mechanism, then build the flux capacitor box.
