Engineered the actuator speed-control mechanism for Actuonix L12 linear actuators using PWM with potentiometer feedback on an Arduino + MATLAB closed-loop pipeline.

Implemented position command, feedback measurement, and automatic adjustment logic to achieve smooth, stable linear motion.

Documented the control architecture using UML activity diagrams to communicate actuator state flow to non-software team members.
