I'm noticing some strange behavior with my PWM code. I'm writing the same value to two pins, but one pin seems to always lag the other by several updates. Here's the related code section:
while(blueVal > blueMax) {
waitMinutes(1);
blueVal -= ((255-blueMax)/20);
analogWrite(blueLeft, blueVal);
analogWrite(blueRight, blueVal);
}
