8.12 Project 12: A Simple Voltmeter
8.12.1 Overview
In this lesson, we will make a simple voltmeter with Raspberry Pi and LCD1602, the range of
this voltmeter is 0~5V. Then, we will measure the voltage of the potentiometer’s
adjustment end with the simple voltmeter and display it on the LCD1602.
8.12.2 Requirement
 Raspberry Pi ×1
 LCD1602 ×1
 Potentiometer ×2
 Breadboard ×1
 Several Jumper wires
8.12.3 Principle
The basic principle of this experiment: Converting the analog voltage that the ADC0832
collected to digital quantity through programming, then display the voltage on the LCD1602.
8.12.4 Procedures
1. Build the circuit
