Hi,
I'm starting an altimeter project. Right now I'm using a 7segx3 display, but in the future I want to display the altitude using a needle, just like the mechanical types.
I'm using one of the motorola pressure sensors and a PIC (still don't know if the pic's ADC will do or if I will need a better ADC).
The fundamental question is:
How digital information can be displayed through an analog needle?
I'm looking for a solution that is easy to implement (few parts), cheap and reliable.
Cheers
