    Add a 10k resistor from Pin 7 to ground.

    It ties the input to ground via the resistor. When you pulled the signal out, it held it's value for a while probably due to capcitance in the line, so by adding the resistor, it quickly drains that capacitance so it reaches low (0v) quicker.

    ahhh I get it. is that the same reason for putting a 10k resistor in the thermistor circuit as well?

    No, the reason for putting the 10k resistor in the thermistor circuit was to set up a voltage divider, you're measuring the voltage over the resistor.

    ahhh ok. theres still a ton I need to learn about circuits. I know the basics, but when it comes to voltage dividers and transistors and stuff I'm lost

    know anywhere I can learn that stuff?
