For our ENGS 21 project, our group decided to make a motorized dynamic splint, which can be seen below.
I worked specifically on the circuit and the code to run the splint. Below is a schematic of the circuit.

It includes many features to ensure patient safety, from angle sensors, physical limits, limit switches, as well as an emergency stop. Here is the circuit while it was in development.

And here is the finalized version.

In addition to the circuitry, this project involved a lot of coding using C. This allowed me to implement features such as a menu, as well as the logic to drive the motor.
This project forced me out of my comfort zone, as I have had very little experience with circuits. It allowed me to add another tool to my engineering toolkit, and it taught me valuable lessons about project management, timeline design, and brainstorming.
