I have tried detecting the color with the actual EV3 to figure out the color value of blue and red but I . I am having trouble reading any of the light values with the EV3 Color sensors. Some of the more notable are: The EV3 Color Sensor can detect 7 colors (and no colors) as opposed to the NXT Color. A lot of improvements have been made.

You need something like the Modern Robotics color sensor that works with emitted light. 1. It's not actually going to work to see the light inside the climber beacon. The Lego color sensor works by shining its own light and seeing which color reflects the most. It resolves a couple of issues that I discovered when I first started working with Lego Mindstorms EV3. The Robocup Junior Australia Rescue. 21 ก.ค. . BertLindeman opened this issue on Jul 17, · 20 comments On ev3-micropython (the system) EV3 and NXT color sensors are not auto-detected. You should also recalibrate the sensor at program startup to account for ambient light. After doing the previous two things, you can measure the reflected light from the surface by shining one of the colored LEDs and taking a sample. If this isn't possible, you can build a shroud over the sensor to block out external light.
