Overview
The goal of this project is to develop a system of sensors that can detect and read the amount of force placed on it, each sensor will have a reading for the left and right foot respectively. We plan to do this by using force sensitive resistors to take in data that is sent to arduino, this data will be used to calculate an imbalance (calculation will take place in arduino) in the forces on each sensor, and display this imbalance for the user. In its final state, the project will be able to find imbalances in forces from pushing with the legs when standing or squatting. Applications for FootFrame could be found in weightlifting and physical therapy, among other places.

Objectives
- Detect the amount of force applied by feet on force sensitive resistors, up to 110 pounds per foot.
- Be able to deliver a reading of the force from each resistor into arduino, and code a program that calculates and displays the difference between the force sensitive resistors in arduino.
- Designing a foot stand that allows us to accurately and completely transmit all the force generated by feet onto the force sensitive resistors.
- Developing an interface to show the information collected (difference in force readings between feet in LBS).
Challenges
- Calibrating force resistors so they do not give inaccurate readings (can sometimes differ by 10%).
- Designing a program to deliver the reading using arduino.
- Making sure the foot stands are stable and do not break, to make sure the user remains safe.
- Making sure all the force is delivered onto the sensor.
- Filtering data to get accurate results.
