3 digits Digital volt meter

[DINESHjp]

i have tried This simple 3-digits digital volt meter.using PIC16F676 used to read analog signal(voltage) and display the value on 3-digits 7-segment from the following link

http://www.coolcircuit.com/project/meter/

vcc and vdd are shown incorrectly in circuit . so interchange them.

but number 0, 4  and 7 is not showing correctly  plz help me

This project is fine but....Did U try build voltmeter specially with PIC or just need 3-digit voltmeter?If U only need voltmeter (not try 2 learn programming & so) there is esiest way to build one-with IC which is made for this purpose ICL7107 or ICL7106.

For starters try this software http://electronicstefan.ilive.ro/ftp/DVM_16F676_HEX/ (username:user & passwd: user)

a simple and very useful project is presented here http://www.tuxgraphics.org/electronics/200903/three-digit-display.shtml with ATMEGA8

i have corrected the code and now its working fine. the other dvm u posted  using atmega8 is also fine and i am using that also  but due to shortage of atmega8 i have to move to this design.
