Sensor readings appear as strange characters

I'm fairly new to Arduino. I have connected the ITG-3200 gyroscope via I2C, and I'm now trying to read the sensor data. I am receiving some data, and it changes when I tilt the breadboard, but all the output is just gibberish characters, like

This is my (partly stolen ^^' ) code:

#define GYROSCOPE 0x69

#include <Wire.h>

int x, y, z;
byte buff[6];

void setup() {
  
    Serial.begin(9600);
    Wire.begin(); 
}

void loop() {
    
    // Delay the flow
    delay(500);
    
    Wire.beginTransmission(GYROSCOPE);
    Wire.send(0x1D);
    Wire.endTransmission();
    
    Wire.requestFrom(GYROSCOPE,6);
    int i = 0;
    while(Wire.available()) {
       buff[i] = Wire.receive();
       i++;
    }
    
    // Convert to ints
    x = (((int)buff[1]) << 8) | buff[0];   
    y = (((int)buff[3]) << 8) | buff[2];
    z = (((int)buff[5]) << 8) | buff[4];
    
    Serial.write(x);
    Serial.write(" ");
    Serial.write(y);
    Serial.write(" ");
    Serial.write(z);
    Serial.write("\n");
}

I'm guessing the problem must be fairly simple to solve... Any ideas? :slight_smile:

Use "print", instead of "write"

... Ok, that was embarrassing ;D

Thanks for the fast reply! :slight_smile:
