Hardware

  • Raspberry pi 3
  • Ultrasonic Sensor - HC-SR04
  • A set of resistors for each sensor you are connecting
    • 330Ω and 470Ω
  • Jumper wires to connect the sensor(s) to the pi

Wire setup

Connecting resistors and jumper wires between sensors and pi

Software

Python


Create a new script

  • Link to repository with script to detect the distance of an object in front of the sensor
Creating a new script in Python 3

Save your script as ultrasonic_distance.py

  • Go to File and click on Save as
  • In the field Save in browse for the C: drive and then select a folder to save in
  • For the field File name type in ultrasonic_distance.py
  • In the field Save as type select All Files
  • Click on Save

Use the terminal to run the script

  • Click on the monitor icon on the top of the screen
  • Type cd "folder name" to change directory to your pythonpractice folder, and hit Enter
  • Type ultrasonic_distance.py and hit Enter to run your program
