Controlling servo motors and LEDs using Python

Having successfully connected the servo motor and LED to our Raspberry Pi, we’ll start writing the Python control code. To facilitate this, we will be using the GPIO Zero Python library, a powerful tool for Raspberry Pi GPIO programming. Our first step in this process will be to set up a Python virtual environment so that we can develop our code.

Setting up our development environment

Just like we did in Chapter 2, we will use a Python virtual environment for our development. As there are libraries that only work with the root installation of Python, we will use system packages in our Python virtual environment. To do this, follow these steps:

  1. On our Raspberry Pi 5, open a Terminal application.
  2. To store our project files, create a new directory by running the following command:
    mkdir Chapter3
  3. Then, navigate to the new directory:
    cd Chapter3
  4. Create a new Python virtual environment for our project:
    python -m venv...
