A color sorter in micro:bit is a simple system that uses a color sensor to detect the RGB values of an object and then sorts it based on the identified color. The sensor reads the light reflected from the object and sends the RGB data to the micro:bit, which then compares the values to predefined thresholds to determine the object’s color, such as red, green, or blue. After recognizing the color, the micro:bit can control a servo motor to direct the object into the correct path, display icons or text on the LED grid, or send the data to another device. This setup usually includes a micro:bit, a color sensor module, servo motors, and a small sorting mechanism, making it ideal for STEM projects, small-scale industrial simulations, and learning basic programming logic.
