This research unveils an innovative FPGA-based architecture for precise control of DC motor speed and direction, leveraging the DE10-Nano board and L298N motor driver to achieve unparalleled performance in real-time applications. By harnessing Verilog Hardware Description Language (HDL), the system orchestrates Pulse Width Modulation (PWM) signals with a 50 Hz frequency to modulate motor speed and digital signals to gov- ern directional transitions via an H-Bridge circuit. A 3-bit switch input interface empowers users to seamlessly select operational states, including stop, forward/reverse rotation, and low/high speed, with duty cycles of 20% and 90% respectively. The design’s modularity facilitates scalability, enabling integration into multi-motor systems for advanced robotics and automation. Simulated using Intel Quartus Prime and ModelSim, the system demon- strates sub-microsecond latency and jitter-free operation, validated through hardware test- ing on a 3 RPM DC motor. Unlike microcontroller-based systems, which suffer from timing inconsistencies, this FPGA-driven solution ensures deterministic signal generation, enhancing reliability in time-critical applications. The L298N driver’s robust interfacing capabilities, coupled with the FPGA’s parallel processing, deliver high-resolution control with minimal power consumption ( 50 mW). This work bridges the gap between recon- figurable hardware and electromechanical systems, offering a scalable platform for smart automation. Potential extensions include closed-loop control with sensor feedback and wireless interfacing for IoT applications. By integrating cutting-edge digital design with practical motor control, this system sets a new benchmark for precision, efficiency, and adaptability in embedded systems, paving the way for next-generation robotic and indus- trial automation solutions.
