Code for Raspi pi

Code for Pi pico

• You can watch all the videos in this playlist if you don’t understand.

• First, try the new code that I sent in Adam_pycode_pid.txt.

• Copy the code from the file and save it into your OiviO Pi.

• Rename the file using the .py extension.

• Then, adjust the PID values:

  • KP controls how strongly the servo reacts to the person’s position.

  • KI helps correct small continuous errors over time.

Adam successfully tested the code that can detect a face and body posture while the servo follows the movement. However, he still needs to adjust the PID so that the servo movement is smoother and more stable

• Open the provided Adam_pycode_pid.txt document file.

• Copy all the code inside the file.

• Paste the code into your Raspberry Pi.

• Save it as a .py file (Example: body_servo_tracker.py)
