3 digits Digital Ammeter using Microcontroller
Digital Ammeter is needed to do any kind of electronics
circuit making. It is very much useful who is interested in electronics
projects. Now-a-days there are many kind of digital or analog ammeter
which are found in the market. But if you make such kind of digital
meter then you have no no bounds happy.

The bellow circuit is digital Ammeter based on PIC16F684 and ACS712
current sensor. Here the measured ac/dc current will display on three
digit 7-segment with resolution 100mA. In this project current sensor
is ACS712ELCTR-30A-T . This circuit can measure the ac or dc current up
to 30mA with 66mV/A output sensitivity.
