Dr. Elena Morales holds a Ph.D. in Mechatronics from the University of Michigan and directs a robotics education lab that partners with local schools to pilot modular electronics curricula. She has 9 years of industry experience designing low-cost, high-impact projects involving infrared sensors, LED driving schemes, and microcontroller interoperability (Arduino/ESP32). Elena has published in IEEE Access on sensor fusion for classroom robotics and led workshops on building reliable breadboard circuits and safe power management. Her writings emphasize practical outcomes, such as implementing door unlock mechanisms and basic servo control, with precise explanations of voltage, current, and resistor calculations tailored for beginners.
