Need guidance for rocket payload

Hey all,

First post here, I have been googling and reading all day, but am having trouble applying hat I find to my my application.

I'm almost brand new to Arduino, and have been tasked with putting this all together.

I need to run a photoresistor and record the data, as well as a gyro and accelerometer. If I could record it all to a single SD card that would be ideal.

I have an Arduino Duemilanove (atmega328) with a MEGAMINI ATMEGA2560 to work with. Any suggestions would be great, pointers, I'm starting from square one here....

Thank you all so much

I guess what I mean is I see all these things done individually, what I am unsure of is running them all together. Do you need more than one Arduino?
