About This Architecture

Arduino Nano ESP32 distance and servo system integrates an HY-SRF05 ultrasonic sensor for real-time distance measurement with an MG996R servo motor for dynamic positioning control. The Arduino Nano ESP32 microcontroller manages sensor input via TRIG and ECHO digital signals on pins D3 and D4, while PWM output on pin D5 drives the servo motor. A 6V battery pack powers both the servo motor directly and the Arduino board, with the 5V Arduino rail supplying the ultrasonic sensor independently. This architecture demonstrates practical sensor-to-actuator feedback loops essential for obstacle detection, robotic arm control, and autonomous navigation applications.
