My idea is to record the acceleration/altitude of a small model rocket launch using these sensors and record all the data onto a microSD card which I'll retrieve afterwards. I'd like to be able to plot all of the data to analyze the performance of the rocket. This data will also help compare the experimental results to the theoretical ones.
(Was only allowed two links so couldn't include barometer)
I have a few questions to make sure that my logic is sound when trying to design this circuit;
1.) Since the OpenLog contains the ATmega328 microcontroller I was going to use the Arduino to write the instructions to this which will initialize the two sensors and start logging data. Is this the correct way to do this? From what I could tell the other sensors did not contain any EEPROM/Flash so there was no way to store any code on there.
2.) If I have multiple sensors running at the same time is this going to cause a data conflict when writing to the SD card? Would it be possible to save two different .txt files, one for each sensor?
