Where is the Light Sensor on a Micro Bit?

The Micro Bit, a popular educational computer, features a built-in light sensor that allows it to detect ambient light levels. This sensor is a key component for various projects involving light detection, such as light-based games, environmental sensing, and robotics.

Location of the Light Sensor

The light sensor on a Micro Bit is a small, circular component located on the front of the device, on the right-hand side (if the Micro Bit is facing you).

It is labeled with the letter “L” and is surrounded by a small black ring, as shown in the image below:

Function of the Light Sensor

The light sensor on the Micro Bit functions as a phototransistor, which means it converts light intensity into an electrical signal. The more light that hits the sensor, the higher the electrical signal it produces.

The Micro Bit’s light sensor can measure light levels ranging from very dark to very bright. It can be used to detect changes in ambient light, trigger events based on light levels, or even measure the brightness of an object.

Using the Light Sensor

To use the light sensor in your Micro Bit projects, you can access it using the following methods:

  • MicroPython: Use the microbit.display.get_light_level() function to read the light sensor value.
  • MakeCode: Use the “light level” block in the input category.

When using the light sensor, keep the following tips in mind:

  • Cover the sensor with your finger or a piece of paper to simulate different light levels.
  • Avoid scratching or damaging the sensor.
  • Use the light sensor with a bright light source for optimal performance.

Applications of the Light Sensor

The light sensor on the Micro Bit has numerous applications in educational and hobbyist projects, including:

  • Light-based games (e.g., light tag, light maze)
  • Environmental sensing (e.g., monitoring light pollution, tracking daylight)
  • Robotics (e.g., line-following robots, light-seeking robots)
  • Home automation (e.g., light-controlled lamps, automatic night lights)

Conclusion

The light sensor on the Micro Bit is a powerful tool for detecting and responding to light. By understanding its location, function, and usage, you can unlock its potential and create innovative projects that interact with the surrounding world.
