Just going through the examples and came across this error in the EsploraLedShow. That is part of the 1.0.3 IDE
// convert the sensor readings to light levels:
byte red = map(xAxis, -512, 512, 0, 255);
byte green = map(xAxis, -512, 512, 0, 255);
byte blue = slider/4;
spot that red and green are mapped to the same axis, it should be:-
// convert the sensor readings to light levels:
byte red = map(xAxis, -512, 512, 0, 255);
byte green = map(yAxis, -512, 512, 0, 255);
byte blue = slider/4;
It is fine in the library examples however.
