    Try this code. Change the output pin.

    unsigned long i;
    void setup() {
    // put your setup code here, to run once:

    OCR0A = 127; //50% duty cycle
    TCCR0A = _BV(COM0A0) | _BV(WGM01) | _BV(WGM00); //toggle output, fast PWM mode
    TCCR0B = _BV(WGM02) | _BV(CS01) | _BV(CS00); // fast PWM mode, prescale 1:64
    pinMode(11, OUTPUT);

    }

    void loop()
    {

    //delay(200); //duration of each frequency
    for(i=0;i<200000;++i){}
    OCR0A += 10; //step size of frequency change
    if(OCR0A >= 245){OCR0A = 10; } //range of sweep, 245 is max.

    }

    This Atmega isn't clever enough to give the outputs you need.

    Hi Etheran,
    Yes, Vin is the power input via diode D1.
    My research was very basic. When you google the topic you can read about some detailed researches done by big companies. The reason the big companies haven't develop a product was that the results aren't good enough.
