Overview
The fitness tracker is implemented using the LSM9DS1 IMU and Adafruit Bluefruit BLE module. It first prompts the user to input their height, weight and goal for the day. It measures the number of steps taken and depending on the person's height, it calculates their stride length which is used to calculate the total distance covered by them. The amount of calories burnt is then calculated with a predetermined formula. We have also used timers to calculate the total time of walking.
