3 Digits Digital Volt Meter with PIC16F676

This is simple 3-digits digital volt meter.PIC16F676 used to read analog signal(voltage) and display the value on 3-digits 7-segment. You can apply similar principles to measure DC current with parallel R shunt.

As we know the most of PIC microcontroller has 8-bit/10-bit on-chip Analog to Digital converter module. In this project I use PIC16F676 which have ADC 10-bits 8 channel but this project use only one channel for measure voltage input for other pin set as digital I/O.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more]
