When someone is injured, often Physical Therapy (PT) is used to aid them in recovering to normal functionality. PT success is largely dependent on patient engagement and tracking data on the recovery process for range of motion and strength factors. Current solutions for tracking this progress are extremely expensive, bulky, heavy, and technically complicated. So after being approached by a PT, I set out to develop an inexpensive and small device that could provide clinicians with a tracking and feedback at a severe fraction of the cost AND ability to modify to their patient needs.

Future goals for this project are to make it a totally wireless solution using Arduino IoT boards, and further development of the device structure to make it more viable for consumer integrations.
To recreate this project you’ll need these materials, and the code linked in github at the bottom: Arduino micro (this will be upgraded later to IoT), flex resistor, lead wires or soldered, breadboard if you prefer, and a resistor to make a voltage divider (I used a 47k Ohm).
