Introduction: Arduino-based Toothbrush Data Monitor

This Arduino-based toothbrush allows you to monitor patterns using 3-axial acceleration data.

Step 1: Step 1: Materials

Toothbrush

Arduino Nano

MPU-6050 3-axis IMU

6ft (1.8m) USB mini-B cable

Step 2: Step 2: Wiring

Connect MPU-6050 and Arduino Nano using wire soldering. See the above picture for detail.

Step 3: Step 3: Programming Arduino

#include <Wire.h>

const int MPU=0x68;//MPU6050 I2C address

int AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;

void get6050();

void setup()

{

Wire.begin();

Wire.beginTransmission(MPU);

Wire.write(0x6B);

Wire.write(0);

Wire.endTransmission(true);

Serial.begin(9600);

}

void loop()
{

get6050();

Serial.print(AcX);

Serial.print(" ");

Serial.print(AcY);

Serial.print(" ");

Serial.print(AcZ);

Serial.println();

delay(15);

}

void get6050()

{
Wire.beginTransmission(MPU);

Wire.write(0x3B);

Wire.endTransmission(false);

Wire.requestFrom(MPU,14,true);

AcX=Wire.read()<<8|Wire.read();

AcY=Wire.read()<<8|Wire.read();

AcZ=Wire.read()<<8|Wire.read();

Tmp=Wire.read()<<8|Wire.read();

GyX=Wire.read()<<8|Wire.read();

GyY=Wire.read()<<8|Wire.read();

GyZ=Wire.read()<<8|Wire.read();

}

Step 4: Step 4: Hit the Serial Plotter and See the Graph

Go to Tools - Serial Plotter (or Ctrl + Shift + L), and you will see the real-time graph with 3-axial acceleration from MPU-6050

Shake toothbrush and see the difference.

    Interesting project! Can you develop about what you do with the data? What kind of information do you get?

    That could be really interesting to see the differences in the way everyone does it!
