I want to track an LED up to 10ft away but the blue LED I am using right now looks white in the center and the pixy has a hard time distinguishing it from background noise. Is there a better color LED to use?
Yes— you need to bias down the camera brightness to get a good color response for your LED. Reduce the camera brightness (in the configuration dialog) until the LED looks blue. It should work well once you get the correct brightness setting.
thanks!
