    Closed: Re: The magical audio filter other opamps?

    you can use ne5534 in place of 741.

    NE5534 has better parameters than 741 like unity gain bandwidth(10Mhz) and high slewrate(13v/µsec) and lower supply voltage.
    Their equivalent noise is...

    Closed: Re: LCD and DFplayer working simultaneously

    you have not included the overall code structure.
    One reason can be that the DFplayer code may contain a wait like routine which returns only after player started.

    is the 'flickering' exist on the monitors from the beginning(when monitor is new ) or is it a new problem surfaced slowly with time?
