/* Project Sunride's UKSEDS 2021 team Avionics.
* An Arduino Nano 33 BLE Sense is used to record acceleration, rate of rotation, air pressure, temperature, humidity and altitude of the rocket itself.
* This data is then stored on an SD Card using the adafruit MicroSD Breakout board.
* The pinout of the BLE Sense can be found here: https://content.arduino.cc/assets/Pinout-NANOsense_latest.pdf
* A link to a tutorial for the SD card board can be found here: https://learn.adafruit.com/adafruit-micro-sd-breakout-board-card-tutorial?view=all
