hi,
The quick way is to buy a panel meter, this link is an example: LASCAR|SP400|VOLTMETER, LCD, 3.5DIGIT, 9PIN | Farnell United Kingdom

LASCAR|SP400|VOLTMETER, LCD, 3.5DIGIT, 9PIN | Farnell United Kingdom

The other way would mean buying a 7106 IC and LCD display.

You could buy a very cheap voltmeter for about £5 and use that as a meter display.
