A command in programming is the name of a function, followed by two brackets. Examples of commands are run(), wait and Motor(). In these brackets we enter the input parameters that the commands require.

The input parameters of a command are the information that it needs in order to execute what we need them to:
- In the "wait()" command we enter an input parameter in the form of a number that indicates how much we want the command to wait. The number itself represents the number of milliseconds the command will wait;
- The "run()" command also has a numeric input parameter. The number represents the speed of the motor in degrees per second, or how many degrees the motor will turn for the duration of one second;
- The "Motor()" command has a more complex input parameter. It requires one of four input options, namely "Port.A", "Port.B", "Port.C" or "Port.D". You can probably guess what they do.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
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 2 - Robotic arm
Introduction
Last time, we programmed our robot to walk around with a platter and a beverage glass, but it couldn't hand the glass to a client. Today we will program a robotic arm to hand out a glass.
Be careful with what speed you will set your robot to move the glass or you may spill its contents!
