There are no errors in that circuit that I can see. It was copied from a proven source, ARRL, it was checked carefully by the owner of the website, and then it was also checked independently by another, so it should be fine.

Well you'll need to calibrate it with a known inductor first, but should be fine.

Bear in mind it only uses a free running oscillator, so it's not going to be very accurate, and it will vary with temperature etc. However, it's going to be plenty accurate enough for reading inductors!.

That looks pretty reasonable, and simple to build - what are you actually wanting to do?.

You might have a look at a commercial PIC based one at https://www.peakelec.co.uk/acatalog/jz_lcr40.html made not far from me!

You don't need to, it's a ready built commercial product, and really small as well - they do a complete range of similar instruments, check the link.

If you're building a homemade one, like in mcs51mc's link above, then you either need a programmer, or someone to program a chip for you.

You use a PIC programmer, you load the code into your computer, and use the programmer to transfer it to the chip.
