This lesson covers how to use the light sensors on the Micro:bit to measure the ambient light. The sensors are useful inputs to perform actions. We use them to respond to the ambient light and dim the Micro:bit LEDs. The input is also used to turn the LED display on or off. This is like the light sensors used in your home.

• Use this lesson to supplement lessons on the environment, light pollution.
• Reference the human eye and how the eye perceives light.
• The code includes comparisons, greater than and less than.
• Make the connections to math concepts.
• The code includes a condition statement. Discuss how computers make decisions.
