Estimating battery SOC with an Arduino and EKF

I built an extended kalman filter (EKF) to estimate battery state of charge (SOC)!
I learned a ton about calculus, circuitry, and coding through this project.
Shoutout to The Limiting Factor for his lithium ion battery simulation!
If you want to learn more about how I built this + see the code, check out my github repo and my article :)
