Hello Friends,
Today we made Digital Voltmeter using PIC16F688. The speciality of this PIC16F688 is it is 14pin PIC and has 10bit resolution and 8 channel A/D converter
The datasheet of PIC16F688 can be downloaded from this site: click here
So why we made this? In one of our project we have to use DVM (digital volt meter) but we were not satisfied with the digital volt meters in the market hence we constructed our own DVM by taking the help of below given site which was very easy to understand as compared to the DVM which was available in market.

Output
The DVM is tested for various input voltages ranging from 0-20 V and found to be very accurate. Some snapshots of the testing are here.

This is a nice project to work on to. But i am living in a place where it is not possible to get such parts like the PIC series. Therefore i wanted to know weather it is possible to get this from your side. I would like to know the price of the project. Therefore kindly do revert back to me if the kit is available for sale or not.

When you've attached the leads as described, you can now connect the meter in series to the device you wish to measure. www.themultimeterguide.com
