    How to measure the current flowing thru the inductor...

    You can measure after the diode on the input of the inductor, use 10 resistors 1R in parallel as a current sense and multiply the scope reading times 10. That should work. Tornado

    How to measure 0-30V with ADC that has 5V maximum input ?

    Re: How to measure 0-30V with ADC that has 5V maximum input Hi Giftbox, can you test the LM358 separate to see if is working properly? It is probably blown by ESD or short circuit or the power polarity connected reverse. Your circuit is correct. Another thing to keep in mind is that LM324 and...
