I have got an idea of designing a micro controller based multimeter with all the features like continuity and some additional features etc but at some reasonable price. Is it practical?

I am sorry I am mistaken all multi meters have controllers in them I think.
Great hobby.I have got an idea of designing a micro controller based multimeter
The AD converter in most micro-controllers is 10bits or less. That is a resolution of 1/1024, or only 20mV on a +-10V scale. Having owned various Fluke digital meters, I wouldn't be happy with such a crude measurement.
My understanding from the teardowns on the eevblog channel
I think that comment applies to 99% of all techie type videos. Most of them could be edited down severely to less than a quarter of their original length. The useful info in most of them could be summed up in about two sentences, and I could read that in less time than it takes the video to start loading.I often enjoy Dave and his video blogs, very informative but he tends to take a bit long to get his point across, and my ADHD usually kicks in before the video is done. A DVM sounds like a good project, just for learning sake.

Are you just using the first PIC as an ADC? Is there an advantage to that rather than just using a dedicated ADC?A more simplified block diagram of what I am currently working with
