Output

When the light sensor detects bright sunlight, the micro:bit signals the servo
motor to lower the shades, providing automatic shading. As the light dims, the
servo motor raises the shades back up, adjusting based on the changing light

levels.

Concepts

1. Light Detection and Response: You will understand how light sensors can
detect changes in light intensity. This connects to the science concept of
light and how it is detected and measured by electronic components. The

robot’s movement is based on the light it “sees,” helping you grasp the
relationship between sensor data and robotic control.

2. Programming and Robotics: This activity introduces you to basic
programming, where they will code the micro:bit to control the robot’s

movement based on the light sensor’s input. This links to robotics and
automation, showing how simple code can direct a machine’s actions in

response to external environmental changes like light levels.
3. Energy Transformation: The robot demonstrates energy transformation,

where electrical energy from the battery is converted into mechanical
energy to power the robot’s motors. you will observe how energy flows from

the battery to power the robot’s movement in response to light signals.

Observations

In the “Building a Simple Robot That Reacts to Light Using Micro:bit” activity,

you will observe how the robot moves towards or away from a light source. As
