Raspberry pi with Python for Robotics 5 - Turning our car

TL;DR

In this tutorial, we learn how to add turning functionality to a Python programmed car using GPIO outputs.

Transcript

what is going on everybody welcome to another python robotics tutorial video in the last video we programmed our little car here to go forward and backwards now we actually want to make the car be able to turn maybe left or right so that's the next thing that we want to do so let's go ahead and do that so uh to start let's do pseudo Nano and I gues...

Questions & Answers

Q: How do we add turning functionality to a Python programmed car?

To add turning functionality, we define separate functions for turning left and right. We set the necessary GPIO outputs, ensuring the correct wheels spin in the desired direction for the specified time frame before using time sleep.

Q: What is the significance of the GPIO outputs in the code?

GPIO outputs determine which wheels of the car spin and in which direction. By manipulating these outputs, we can control the turning of the car.

Q: How do we ensure the wheels spin correctly for turning left?

To make the car turn left, we set GPIO output 7 to true, GPIO output 11 to true, GPIO output 13 to true, and GPIO output 15 to false. We also include the necessary time sleep and GPIO cleanup commands.

Q: How do we ensure the wheels spin correctly for turning right?

To make the car turn right, we set GPIO output 7 to false, GPIO output 11 to false, GPIO output 13 to false, and GPIO output 15 to true. Again, time sleep and GPIO cleanup commands are included.

Summary & Key Takeaways

• The video demonstrates the process of adding turning functionality to a Python programmed car.

• The code involves defining functions for turning left and right, setting GPIO outputs accordingly, and using time sleep for the desired time frame.

• The tutorial also mentions the need for pivoting functionality and mentions it will be covered in the next video.
