Supports alternativ PWM frequencies for MEGA2560 Attention! Timer0 is also used for other tasks (millis, micros, delay). Timer0 = D4 and D13 Timer1 = D11, D12 Timer2 = D9, D10 Timer3 = D2, D3, D5 Timer4 = D6, D7, D8 Timer5 = D44, D45, D46 Prescaler 1= 31372,55Hz, 2= 3921,16Hz, 3= 490Hz, 4= 122.55Hz 5= 30Hz (in case of timer0 the PWM frequency for prescaler values 1-5 are doubled)

increments and decrements a number , the output can presettet with the offset input
