Lesson 19: Water Level Monitoring - Elecrow Raspberry Pi & Arduino Starter Kit User Manual

By running the program it will show the value of the potentiometer, to change the value need to turn the
potentiometer physically left or right, this will change his value.
LESSON 20: WATER LEVEL MONITORING
Introduction
This is a water level measurement experiment, it is relatively simple to achieve, only need to read the value of the
analog port (A0 or others), and then converted to a percentage.
We'll be using the PCF8591 module as well for the water level monitoring example.
