For my graduate electronics course, I developed an electric aircraft motor testbed through a series of hands-on labs. The project involved building motor driver and power circuits, implementing PWM motor speed control, and adding an infrared tachometer for real-time RPM measurement. I then integrated voltage, temperature, and inertial sensors, and programmed a closed-loop control system to maintain constant propeller speed. Finally, I extended the system with IoT connectivity for wireless monitoring and control over an MQTT network.
