BNO055 SERIAL LIBRARY DRIVER
To use this driver you will also need to download the Adafruit_Sensor Which provides a common 'type' for sensor data and some helper functions. * This driver uses the Adafruit unified sensor library (Adafruit_Sensor), And of course, The toggle on/off button still makes a new file every time you do that! Does anybody know why arduino thinks a file doesn't exist? and when you plug the microSD into a computer, Var file is on the card. and it doesn't! But, if the file doesn't exist, the SD library should create one when you try to open it. I trouble shooted for a while and then used the SD.exists() fuction to see if var file even exists. However, right now, whenever the arduino tries to read "var file" it sees nothing. That way when you power cycle the SD library can read var file and go to that file number instead of restarting at file one and overwriting data from before. To do that, I made a file named "var file.txt" to store what file the SD is on.

( since this will be powered by a battery, I need to be able to turn it off and on to conserve battery). And every time I push the toggle on/off button, I have it open a new file to write orientation data to(all named 1 number higher than the previous file), But my project right now is to open a new file number, again one higher than the last one created, when power is turned off and on again. I am sucessfully taking data from the 9dof and recording it on the SD. My components are a outsourced SD card reader very similar to the sparkfun SD reader ( ), an Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055 ( I tried to use the sparkfun 9dof sensor stick, but There was just no figuring it out, so I had to go with this one) and an arduino uno. I have a project where I am attempting to log data from a 9 degrees of freedom sensor to an SD card.
