Installing Basic Robot Control Software for Python
Many robot projects are programmed in Python 3, using the GPIO hardware and code interface.
Check and Install
Access the RaspberryPi directly from a desktop terminal or through SSH and then install GPIO Zero with the following commands:
% sudo apt-get update && sudo apt-get upgrade
% sudo apt-get install python3-pip python3-gpiozero
The command response should inform if the software is already installed and if updates are available.
