IDC2018IOT Leg Running Tracker

We came out with this idea as part of the “Internet Of Things” course at IDC Herzliya.
The project’s goal is to enhance physical activities that involve running or walking using NodeMCU, a few sensors and a could server. The result of this project is a very useful IOT device that can be turned in the future to a real production product that will be used everywhere! Please let us know what you think :)
Before you start, make sure you have:
NodeMCU device.
1 Piezoelectric sensor.

MPU6050 sensor.
One big matrix.

Elastic rope.
Firebase account.

Optional:
Multiple Piezoelectric sensor_
