Supported pwm pins (Arduino Leonardo/Micro): 5, 9, 10, 11
Create an instance: normal mode (0 to max) Dimmer32u4 channel1(pinnumber);
or inverted mode (max to 0) Dimmer32u4 channel2(pinnumber, true);
Instance initialization: channel1.init(); channel2.init();
Functions: getMaxValue(): returns max possible value.
setValue(value), where value=0..maxValue sets timer to "value" duty-cycle
