Lesson 40 How to Make a Simple Voltmeter(2)
Introduction
In this lesson, we will learn how to make a simple voltmeter based on ADC0832 and
LCD1602.
Components
- 1 * Raspberry Pi
- 1 * GPIO Extension Board
- 1 * 40-Pin GPIO Cable
- 1 * Breadboard
- 1 * ADC0832 Module
- 1 * I2C Interface Module
- 1 * Slide Potentiometer Module
- 1 * LCD1602
- 2 * 3-Pin Wires
- 1 * 4-Pin Wires
- 1 * 5-Pin Wires
Experimental Principle
In this experiment, we program the Raspberry Pi to read voltage(DC0-5V) via ADC0832,
and then display the voltage value on the LCD1602.
