If you want to connect a rotary switch up without using all your digital pins, this is the video for you.

In this video I'm going to explain how you can use 1 analog pin on an Arduino to connect up to any pin amount rotary switch.
This is an alternative method to connecting up the pins of the rotary switch to your digital input pins, As it requires you to connect up each pin to a digital input and can take up a large portion of available pins on your Arduino.

This method can be used on most microcontrollers such as Arduino, RaspberryPi, ESP32, ESP8266 ect. as long as an analog pin in available.

If you are after the code I was using:
