III. METHODOLOGY

A.  Hardware Setup

The hardware setup involved the integration of a high-torque servo motor (Model SG 90) with the NodeMCU microcontroller. The servo motor featured a 180-degree rotation capability and a positioning accuracy of ±0.5 degrees. The servo motor was mounted inside a custom-designed rectangular enclosure made of cardboard keeping the project more echo friendly. The enclosure dimensions were 10 cm x 6 cm x 4 cm, with an open side to accommodate the actuating rod mechanism.

B. Actuating Rod Mechanism

The actuating rod mechanism consisted of a rigid stainless-steel rod (3 mm diameter) connected to the servo motor's output shaft. The rod length was optimized to provide adequate displacement for pressing the target switches or buttons. The rod was securely attached to the servo motor using a coupler, ensuring precise and reliable actuation.

C. NodeMCU Microcontroller

The NodeMCU microcontroller, based on the ESP8266 Wi-Fi module, was selected for its robust wireless connectivity and computational capabilities. It operated at a clock speed of 80 MHz and featured 4 MB flash memory for storing the firmware code and configuration parameters. The microcontroller was powered by a 5V DC input, supplied via a USB connection from a standard phone charger.

D.  Firmware Development

The firmware code was developed using the Arduino IDE, leveraging the Arduino core for ESP8266. The code incorporated servo motor control libraries and utilized the Servo.h library for precise servo motor positioning. It implemented a proportional control algorithm to ensure smooth and accurate actuation of the target switches. The firmware code was optimized for efficient memory usage and minimal power consumption.

E. Wireless Control Integration

The portable wireless switch controller was integrated with the Blink app, available for Android and iOS platforms. The NodeMCU microcontroller established a Wi-Fi connection with the smartphone running the Blink app, leveraging the MQTT protocol for reliable and  secure communication. The Blink app provided a graphical user interface (GUI) with virtual buttons, allowing users to control the target switches remotely. The app supported real-time feedback and status updates, enhancing user interaction and system monitoring.

F. Testing and Validation

The implemented system underwent rigorous testing to validate its performance and reliability. The servo motor's angular displacement accuracy was measured using an optical encoder with a resolution of 0.1 degrees. The response time of the wireless communication was assessed by measuring the round-trip time (RTT) between the Blink app command and the corresponding switch actuation. The system's range was evaluated by measuring the maximum distance at which reliable control was maintained, considering factors such as signal strength and interference.

G.  Data Collection and Analysis

Various performance metrics were collected during the testing phase, including angular positioning accuracy, RTT, range, and power consumption. Statistical analysis, including mean, standard deviation, and correlation analysis, was performed to analyze the collected data. User feedback surveys were conducted to assess the usability and user satisfaction aspects of the portable wireless switch controller. The collected data and analysis provided insights into the system's performance, reliability, efficiency, and user acceptance.
