What does the OP expect to do with the data? 40KHz samples are too fast for the serial port.

DSG, do you want to answer this question?Roff said:This is a can of worms.
Do you prefer surface mount (SMT) or thru-hole components?

EDIT: The reason this is important is that not all parts, especially ICs, are available in through-hole, and vice-versa.
Why do you ask? I've provided ConvStart from pin 3 of the 555.blueroomelectronics said:What does the signal on pin 2 of the 555 look like?
Is the PIC comparator as fast as the LM393 (which is no speed demon)? The discrete Microchip comparators I looked at were much too slow (4us).blueroomelectronics said:Why to get rid of the 555 of course, most PICs have comparator inputs that might work just as well. Timing done digitally too.
The PIC also has a sample & hold cap built in. No real need for the CD4016.
OK, here it is.blueroomelectronics said:Can you post an simulated image of the pin #2 signal?
I don't have the time or inclination to do the OPs project for him. I'll help but I'm not going to build the thing.
PS I wonder if the OP has the programming skills required to complete the project?
