ADEEPT Ultimate Sensor Kit for Raspberry Pi - Lesson 38 Make a Distance Measuring Device

Lesson 38 Make a Distance Measuring Device
Introduction
In this lesson, we will learn how to make a distance measuring device based on ultrasonic
module and LCD1602.
Components
- 1 * Raspberry Pi
- 1 * GPIO Extension Board
- 1 * 40-Pin GPIO Cable
- 1 * Breadboard
- 1 * LCD1602
- 1 * I2C Interface Module
- 1 * Ultrasonic Sensor Module
- 1 * 4-Pin Wires
- 4 * Jumper Wires
Experimental Principle
In this experiment, we program the Raspberry Pi to detect the distance between the
obstacle and ultrasonic module, and then display the data on the LCD1602.
