Seeking Help Transitioning from Line Following to Wall Following

[kcmsaum58]

I'm working on a line-following robot with PID control and three sonar sensors. My primary challenge is transitioning from line following to wall following when the line ends. How can I smoothly make this transition using sonar sensors for guidance?

Any insights or code examples on achieving this transition effectively would be greatly appreciated.

Thank you for your assistance!

You will have better results if you keep the topic on one thread. Add more information about your work on your project (on the first thread) and narrow the goal, aiming for solving one task at a time. "Line follower" means a lot of interaction to some users.

Line follower With Sonar Sensor

Hello, Arduino community, I hope everyone is doing well. I'm currently working on an Arduino-based line-following robot project, which incorporates PID control for line following. My robot is designed to handle various line conditions, including 90-degree turns, T-sections, and black-white lines. However, I've encountered a specific challenge in my project. There may be instances where my robot encounters dead-end lines or line breaks of approximately 5 cm. To address this challenge, I've equi…
