Wire setup
Software
Python
Create a new script
- Link to repository with script to detect the distance of an object in front of the sensor
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
