Methods: First the OLED was wired to display text. This text was then updated to update every 3 seconds with the temperature read in from the temperature IC.

The esp-32 was then programmed to connect to the WiFi and through the thingspeak API, upload the temperature data.

Then a pushbutton was added to switch the WiFi ssid and password from my home network to the school's guest network
