I am working on a project that requires a measurement of acceleration. I have a ADXL345 accelerometer, an aduino and a MAX7219 dot matrix display. I need help setting up a code for my aduino to display the acceleration from the ADXL345 accelerometer onto the MAX7219 display. Please help!

Expert Solution

connections are as follos

matrix connection

copy the below code it display accelerometer reading of x direction

//Arduino, adxl 345 and Dot Matrix Display
/*********** COMMUNICATION SELECTION ***********/

#include "LedControl.h" //include library for interfacing MAX7219
LedControl lc=LedControl(12,11,10,1);

#include <Wire.h>
#include <FaBo3Axis_ADXL345.h>
FaBo3Axis fabo3axis;


int display;

void setup()
{
Serial.begin(9600);
Serial.println("Checking I2C device...");
  
if(fabo3axis.searchDevice()){
Serial.println("I am ADXL345");
}
Serial.println("Init...");
fabo3axis.configuration();
fabo3axis.powerOn();
}

void loop()
{
int x,y,z,tensplace,hundredsplace,onesplace;  

fabo3axis.readXYZ(&x,&y,&z);
onesplace = x%10;
x=x/10;
tensplace=x%10;
x=x/100;
hundredsplace=x%10; // you can replace x by y to get acceleration along y axis

display=hundredsplace;
call_display();
delay(500);
display=tensplace;
call_display();
delay(500);
display=onesplace;
call_display();
delay(1000);
