+NOTE I DID NOT FOLLOW THIS PROPERLY. 
+I just used the internal pull-down resistors, and didn't wire properly to ground. Look at the wall if you want to see how it's wired better.
+Can you tell I didn't know what I was really doing?
+If repeated or changed for other doors, maybe follow this guide a bit better, or update this README to what we standardise it to. 
+I also changed to using GPIO 18 as I destroyed the original pin. Woops!

 The Raspberry Pi Pico W is powered by a standard 5V USB Micro B power supply.
 
 GPIO 22 is pulled up to 3.3V with a 10K ohm resistor. This external pull-up resistor is stronger than the Pico's internal pull-up resistors that can be configured on the GPIO pins and helps reduce the effects of ESD on the long wires from the Pico to the reed switch. GPIO 22 also has an optional 1K ohm current-limiting resistor (even a lower value like 100 ohms is fine) to protect it from shorting to ground in case it is misconfigured as an output pin.
