• When you press both buttons A and B, the servo motor will move 45 degrees.

Concepts

1. Basic Motor Control: you will learn how to control a motor using signals
from the micro:bit, either to start or stop the motor or to control its speed
and direction. This concept helps them understand how electrical signals

control the movement of mechanical parts, a fundamental idea in robotics
and mechatronics.

2. Microcontroller and Actuator Interaction: You will explore how the
micro:bit acts as a brain that sends electrical signals to an actuator (the

motor). This connects to the idea of microcontrollers being used to control
physical components in automated systems, providing a foundation for
understanding more complex systems like robots and automated machines.

3. Power and Energy Transformation: This activity demonstrates how
electrical energy is converted into mechanical energy through the motor,
which powers the rotation of the motor’s shaft. you can connect this to the

science of energy transformation and see it in action.

Observations

In the “Controlling a Motor Using Micro:bit” activity, you will observe how the
motor responds to the commands they program into the micro:bit. They will
see the motor start, stop, and change speed or direction based on the signals it
