Light sensing projects for your class
Projects and lesson guides to get the most out of the BBC micro:bit light sensor
Light sensors are input devices. They are used to detect changes in light levels and can be programmed to use this environmental information as an input to carry-out further instructions in computer systems. For example, you can code the micro:bit to make a night light that shines brightly when the light sensor senses it is dark; when the light levels are very low.
The micro:bit uses the LED display as the light sensor. The LED display performs two functions on the micro:bit, to light up and glow brightly and to also detect, measure and respond to the level of light wherever it is placed.
The light sensor is a great sensor to pick for teaching control systems because you can test it so easily. For example, shine a torch on it or cover it with your hand and get instant results.
This video explains how light sensors are used in real-world products and could give inspiration to your students to make their own.
