  • Instructions say to pair with a fixed code 0000 or 1234 (mine uses 1234). Does bluetooth pairing set up a unique session such that I can have several people racing i-Racers next to each other without conflicts?

  • Use analogWrite(pin, {0:255}). Look at the RGB value as intensity where the LED is brightest as it approaches 0 (voltage goes up) and off at 255. You ‘mix’ colors by playing with the three intensities. Even at 240ish you see influence so by the time you are down in the 100s across all three colors you will likely just see white. Try Red at 220, Green at 0, and Blue at 255 and you will probably get a nice Yellow. A piece of clear plastic over the top helps diffuse the color.

No public wish lists :(
