ADEEPT Ultimate Sensor Kit for Raspberry Pi - Lesson 39 How to Make a Simple Voltmeter(1)

Lesson 39 How to Make a Simple Voltmeter(1)
Introduction
In this lesson, we will learn how to make a simple voltmeter based on ADC0832 and
segment display module.
Components
- 1 * Raspberry Pi
- 1 * GPIO Extension Board
- 1 * 40-Pin GPIO Cable
- 1 * Breadboard
- 1 * ADC0832 Module
- 1 * Segment Display Module
- 1 * Slide Potentiometer Module
- 2 * 5-Pin Wires
- 2 * 3-Pin Wires
Experimental Principle
In this experiment, we program the Raspberry Pi to read voltage(DC: 0-5V) via ADC0832,
and then display the voltage value on the segment display module.
