guage volt meter for bike

how to do a digital volt meter guage for bike?

EDIT: Moved to correct forum by Moderator!.

You mean an batery voltage mether?

there are modules and ICs for meshuring and deisplaying voltage.
There are methers that display it on an LCD,7 segnent LED or an simple LED bar

but how to make??
got any circuit?

We have www.google.com you know

There are difrent way of displaing the data.Numeric LCD,DotMarix LED,7 segment LED,LED bar...

cuipin,

you have to provide a bit more info.
what kind of bike (motor or pedal power) and what exactly you want to display? battery voltage or something else? (wind resistance, road incline, azimuth, tank level, fuel efficiency, travel speed, travel distance, humidity, temperature, ...)
if it's just the battery voltage, maybe it's cheapest to buy small digital multimeter (i've seen some for $5-6). lot's of people like to use LED bargraph.
