A smart switchboard provides convenience by allowing users to remotely control their electrical devices and appliances through a mobile application or web interface. It also offers energy efficiency by monitoring energy usage and promoting adjustments for lower consumption and bills. In this paper we developed a smart panel for wireless control of lights and appliances, including fan speed control, using the Blynk app. A system was also implemented to display and cut off power supply if current or voltage exceeded a set limit to prevent harm to the appliance. The project demonstrated successful implementation and improvement of basic appliance control and safety measures.
Automated switchboards, also referred to as smart panels(Switchboards), have become increasingly popular due to their capability to remotely control and monitor various electrical appliances and devices. These switchboards utilize wireless communication technologies such as Wi-Fi, Bluetooth, and Zigbee, which enable users to control and monitor their electrical appliances from anywhere at any time, through a mobile app or web interface, offering them convenience and flexibility. Apart from convenience, automated switchboards offer added safety features by using sensors to detect changes in the environment, such as temperature, humidity, and motion, which can help prevent accidents or damages. For instance, if the temperature in a room exceeds a certain threshold, the switchboard can automatically turn on the air conditioning system to regulate the temperature. Moreover, automated switchboards offer energy-saving benefits by monitoring the usage patterns of various electrical appliances and identifying areas of high energy consumption. This information can be used to suggest ways to reduce energy usage, such as turning off lights and appliances automatically when not in use or optimizing the use of solar energy based on weather forecasts. Automated switchboards have a wide range of potential applications in various industries, such as homes, offices, hospitals, and factories. In the healthcare industry, for instance, these switchboards can monitor patients' vital signs and regulate the environment to provide optimal conditions for their recovery. Overall, this research paper will provide insights into the design and implementation of automated switchboards, the benefits they offer, and their potential applications in various industries, making it a valuable resource for researchers, engineers, and enthusiasts interested in the field of automation and smart technologies.

The Project is divided into 3 phases
Phase 1: Wireless Control of Fans and Lights: The first phase of the project concentrates on enabling wireless control of fans and lights in a room. To achieve this, the ESP-8266 microcontroller is utilized to manage relay modules connected to the respective appliances. By integrating the Nodemcu and relay modules, the system allows users to remotely toggle the lights and fans on and off. The Blynk mobile application is employed as an intuitive and user-friendly interface for wireless control.
Phase 2: Fan Speed Control: Expanding upon the wireless control capabilities established in Phase 1, Phase 2 introduces fan speed control functionality. The LN298N motor driver is employed to enable precise regulation of fan speed and direction. By employing the H-bridge configuration and pulse-width modulation (PWM) techniques, the Arduino Uno, serving as a controller, adjusts the fan speed according to user preferences.
Phase 3: Integrated Circuit Breaker Mechanism: In Phase 3, the emphasis shifts towards implementing an integrated circuit breaker mechanism to ensure safety in scenarios involving excessive current consumption. The ACS712 current sensor is utilized to measure the currents supplied to individual appliances. This data is then displayed on the mobile application, providing users with real-time feedback. Moreover, a predetermined threshold is established, and if the current surpasses this threshold, the relay modules automatically disconnect power to the specific appliance, mitigating potential hazards.
