High Precision Analog IO With Digital Pins
https://hackaday.com/2019/07/22/high-precision-analog-io-with-digital-pins/
Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every conceivable microcontroller and platform. Plug that into your Arduino and boom, temperature (and humidity!) readings.
