Rocket Altimeter

[murphy6]

Hello Everyone,
I am looking for instructions, schematics, and PICBASIC programming code for a rocket altimeter. My friends and I are new to using PICs and PicBasic so we need a detailed schematic and PicBasic program. I have noticed that there are some postings for altimeters, but we are using the 16F84(a). If someone could help us with any of these things it would be much appreciated. We have been working through some simple projects to get familiar with PICBASIC. Please, we only have PICBASIC not PICBASIC PRO.

PS we are thinking of using a pressure sensor because its easier???

Thank You
