hi
i am using a 2.7khz magnetic buzzer.i am driving it through a pwm pin.i am trying to control the volume.the volume differs in the range of 0 to 50% duty cycle but the response is flat in a long range from 5% to 17% and 17% to 35%;
i want to acheive 5 steps of volume.setting the volume in the range above creates different volume steps but the firs and 2nd step are too low and second and third are two high again the fifth is very close to the fourth step.
Please suggest what can be done

Thanks
Best Regards
