Hello! I am brand new to coding and was thrown into an extremely technical project and I am not sure how to go about doing it. We are doing a project with a Wilberforce Pendulum and are using an Arduino uno, MPU 6050 6 dof sensor and the Bluefruit LE UART friend. I have everything running great separately in different codes. I have no idea wether or not I need to connect anything to the breadboard so that they can read together. Here are the two separate codes I am truly at a loss I really have no idea how to put these together so that it will work seamlessly.
Bluefruit Code
#include <Arduino.h>
#include <SPI.h>
#include "Adafruit_BLE.h"
#include "Adafruit_BluefruitLE_SPI.h"
#include "Adafruit_BluefruitLE_UART.h"
#include "BluefruitConfig.h"
#if SOFTWARE_SERIAL_AVAILABLE
#include <SoftwareSerial.h>
#endif
/*=========================================================================
APPLICATION SETTINGS
FACTORYRESET_ENABLE Perform a factory reset when running this sketch
Enabling this will put your Bluefruit LE module
in a 'known good' state and clear any config
data set in previous sketches or projects, so
running this at least once is a good idea.
When deploying your project, however, you will
want to disable factory reset by setting this
value to 0. If you are making changes to your
Bluefruit LE device via AT commands, and those
changes aren't persisting across resets, this
is the reason why. Factory reset will erase
the non-volatile memory where config data is
stored, setting it back to factory default
values.
Some sketches that require you to bond to a
central device (HID mouse, keyboard, etc.)
won't work at all with this feature enabled
since the factory reset will clear all of the
bonding data stored on the chip, meaning the
central device won't be able to reconnect.
MINIMUM_FIRMWARE_VERSION Minimum firmware version to have some new features
MODE_LED_BEHAVIOUR LED activity, valid options are
"DISABLE" or "MODE" or "BLEUART" or
"HWUART" or "SPI" or "MANUAL"
