Help sending and saving multiple values from Arduino to Processing

#1

Hi,
I’m new to coding with processing, so apologies in advance for rookie mistakes. I’m working on a project where I’m collectiog multiple orientation angles from 2 BNO055 sensors using Arduino. The idea is to create an interface using Processing, where if I press the ‘DATA’ button, the angle values get stored as a .csv file to be used later (I’ve attached a pic). I will be very grateful if you could! Please help me…Picture1

Here is my Arduino code:

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BNO055.h>
#include <utility/imumaths.h>
#include <Volume.h>

// The two BNO055 modules, bnoB has the ADR pin wired to 3.3v to change its i2c address
// Both are wired: SCL to analog 5, SDA to analog 4, VIN to 5v, GRN to ground
Adafruit_BNO055 bnoA = Adafruit_BNO055(-1, BNO055_ADDRESS_A);
Adafruit_BNO055 bnoB = Adafruit_BNO055(-1, BNO055_ADDRESS_B);

int xA; int yA; int zA;                               //First Measure Forearm
int xA_f; int yA_f; int zA_f;                         //Fol0ing Measures

int xB; int yB; int zB;                                             //First Measure Upper Arm
int xB_f;int yB_f;int zB_f;                                         //Following Measures

int vibpin = 9;                                                     //Pin Number for Vibrating Motor
int buzzpin = 7;                                                    //Pin Number for Buzzer

   Serial.setTimeout(500);                                           // The program waits 50ms after which input won't be taken
   //Serial.println("Orientation Sensor Test"); Serial.println("");
   pinMode(9, OUTPUT);
   pinMode(7, OUTPUT);
   //Check that both the sensors are correctly mounted
   if(!bnoA.begin()) {
       Serial.print("Ooops, BNO055(A) not detected");
       while(1);
   }
   bnoA.setExtCrystalUse(true);

       Serial.print("Ooops, BNO055(B) not detected");
       while(1);
   } 
   bnoB.setExtCrystalUse(true);

   Serial.println("Be Ready for First Measure in 1 secs"); Serial.println("");
   
   delay(1000);

   //Take the first orientation angles that we will later compare with the fol0ing ones

Hi, what exactly is your problem? Difficult to help without stating one =)

Also go have a look in other threads in the forum, there are plenty about that subject.

Nice project!
well, first you will need Serial Communication between arduino and processing IDE.
see: https://learn.sparkfun.com/tutorials/connecting-arduino-to-processing/all

Capture every data sent from the arduino and then save it to .csv
see: https://forum.arduino.cc/index.php?topic=56789.0

hope you get where to start!
