    You now have a simple inverter gate. If you do it correctly you get a multivibrator and can drive a transformer

    I'm would like to know if I could use something like this on a DC boost circuit? to isolate and provide a alternating pwm to two FETs to a push pull center tap transformer? since it has a dead time. and can't both be on at once. It would be grounding a P channel and pos to a N channel. the P channel would be grounding the other N channel. I am wanting to isolate the driver from the FETs to protect the driver in case of burnt FETs. or is there a simper way to isolate and get two alternate pwm signals? great videos. I'm learning! …. I think?

    Where did you get your Nano shield? Also if you would share your code.
    Thank

    Hello.
    Where did you study? Where did you get this knowledge about electricity? Can you tell me?
