Caloriemeter and Activity tracker

Hello  Everyone,My name is Harji Nagi.I am currently second year student studying electronics and communication engineering in India.

Today I made a smart  "Calorie Meter and Activity Tracker" via Arduino Nano ,HC-05 Bluetooth Module and MPU-6050MPU-6050 device which is a perfect combination of 3-axis accelerometer and 3-axis gyroscope.This device can calculates your calories by counting number of steps and plots X,Y,Z graph on your monitoring device(Mobile).

The Component list are:

1)Arduino Nano

2)HC-05 Bluetooth Module


4)Voltage Regulator 3.3V

5)Ceramic Capacitor 100nf

6)Electrolytic Decoupling Capacitor 10uf/25V

7)Lithium Polymer Battery 7.4V

8)Some Male to Male Jumper Wires

The MPU-6050MPU-6050 is the motion tracking device designed for the low power,low cost and high performance. .The MPU-6050MPU-6050 send its data via Hc-05 Bluetooth module to your connected mobile devices.For precision tracking of both fast and slow motions and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.
