Variables are like small boxes inside the computer that store important information for us. Imagine the following situation:

The await command tells your robot:
“Wait until this action is finished, then continue!”

Why use "await"?

• Motors need time to move
• Sounds need time to play
• Sensors need time to read values

Without "await", the robot may move on too quickly and not finish its actions properly.

Important rule

You can only use "await" inside an "async" function.

async def main():
    await motor.run_for_time(port.A, 1000, 1000)

We already know how to set the speed of the motor and how long it should move. However, with these commands alone, we cannot control exactly how many degrees the motor turns. To make the motor turn a specific number of degrees, we need to use some simple math.

The motor speed is measured in degrees per second. We can use this to calculate how much the motor will turn using the formula:

S = V * T

S – the distance traveled (in this case, the number of degrees the motor turns);

V – velocity (degrees per second);

T – time (in seconds).

Before we can run Python programs on the robot, we need to open the SPIKE software, create a Python project, and connect the Hub to the computer. In this tutorial, you will learn how to do each of these steps using the LEGO SPIKE software.

During this course, we expect the following from you:

• Ask questions when you are curious or need help.

• Don’t be afraid to make mistakes - this is how you learn.

• Share your ideas, help others, and be open to receiving help.

• Listen carefully when the teacher is speaking - it’s important for everyone.

• Read your lesson before coming to class.

Ask questions!

The teacher does not expect you to know everything. What matters is that you ask when you don’t understand something. Go to your teacher when you need help - they can support you only if you ask.

It’s okay to make mistakes

It’s normal not to succeed the first time. Learning takes practice. Keep trying, testing, and improving your solution until you succeed.

Work as a team

The whole class is a team. Help each other, share ideas, and learn together. It’s okay to give hints or learn from others - this helps everyone improve.

Listen when the teacher speaks

When the teacher is explaining something, it is important for everyone. You might hear a solution to a problem you will face later.

Prepare before class

You will have access to e-textbooks that you can read at home on a phone, tablet, or computer. Try to think about the tasks in advance so you are ready to work during the lesson.

Resistors are essential electronic components that limit the flow of electric current in a circuit. Because they’re so small, their resistance value (measured in ohms, Ω) is usually marked with colored bands instead of numbers. Here's how to read them:
