This variable tells the run_time command whether or not to wait until it has fully executed or to continue executing other commands while simultaneously driving the motor.
When we do not pass this parameter, it accepts "True" as a default value and the program waits for the command to fully complete.
This parameter allows you to use the run_time command to drive both motors simultaneously.

Python with LEGO Mindstorms EV3 - Level 1
The course introduces students to the programming language Python. We use LEGO Mindstorms EV3 Robots. Python is a popular programming language. It could be used for introducing students to programming, for academic studies, for developing machine learning algorithms and as a general-purpose language.
During the course, students learn how to read and how to develop Python programs. They use an Integrated Development Environment called Visual Studio Code. Robots are programmed to perform interesting and funny tasks like "bringing you water". The level ends with competition on a playing field with boxes.

Lesson 3 - Luna 3
Introduction
Today we are going to look at a favorite historic moment of ours, namely the Moon landing by the Luna 3 spaceship. Our robot is also called Luna 3 and we will choose an object to represent The Moon.
The robot will go around the "Moon", take a picture and return to base. We will take the picture with a phone set to "continuous shot" or a timer.
If you work fast, you will have a picture at the end of the lesson that you can use to remember it.
