3# This is a somewhat straightforward program that relies on my raspberry pi
4# It sends a request like an api request to the raspberry pi in the form of a 1-time socket (the socket is disposed of after every request), then the raspberry pi returns what keys on my 16-key keypad/key matrix are pressed
5# The server will be up a lot more now that I have a blower fan blowing on it that is held by legos, with a 9V battery hooked up to it
6
7# Sending requests with a delay faster than .1s will just make the returned value innacurate 
8# Port may change from time to time
9
10# IMPORTANT: 
11
12# WILL NOT RUN CORRECTLY IN SOLOLEARN, VISUAL STUDIO OR VISUAL STUDIO CODE IS REQUIRED
13
14# ALL REQUESTS ARE LOGGED, REQUESTER'S IP IS ALSO LOGGED
15# IPS ARE NOT LOGGED OR PUBLICISED IN ANY WAY
16# IP LOGGING IS ONLY FOR SECURITY PURPOSES, WIHOUT MALICIOUS INTENT 
17# YOU MAY ASK TO HAVE YOUR IP REMOVED FROM THE LOGS
