LEGO MINDSTORMS Robot Inventor
This build for this simple project is just the color sensor on a stick. Two programs let you use the sensor like a meter to scan objects for both color and reflected light intensity. Both programs show the detected color by changing the color of the hub center button. The simpler program displays reflected light intensity using a bar graph of 0-5 bars of "signal strength". The more complex program uses all 25 pixels on the display to show 26 different levels of intensity.
For a more advanced version of this idea, see the Sensor Meter.
