This research presents the design, development, and implementation of a mini smart car prototype that operates using Internet of Things (IoT) technology. The system is built around the ESP8266 microcontroller (Amica version), which functions as the core processing unit responsible for handling Wi-Fi communication and data processing. The motion of the car is controlled by an L298 motor driver module that regulates the operation of DC motors. The entire system is powered by a 3.7-volt rechargeable battery, ensuring portability and energy efficiency. The study discusses in detail the hardware configuration, software programming, and integration of IoT-based control through a web or mobile interface. Functional testing of the prototype, named MINIOT, focuses on evaluating the responsiveness, stability, and reliability of remote control operations. The results are expected to show that the system can effectively receive and execute user commands while transmitting real-time telemetry data, such as motor status and connection indicators. This project demonstrates the feasibility of low-cost IoT-based automation for small-scale robotic applications.

Growing demand for electricity savings has led to the development of an automatic LED emergency light system. It is based on providing light when the power is cut off. Once fully charged, the battery ceases charging, and in the event of a power failure, the LEDs are automatically powered by the battery. The project focuses on two primary functions: it automatically activates during power outages to give illumination, eliminating the need to search for the switch, and the battery rapidly begins recharging as the main power is restored. The emergency light is crucial due to the inconsistent voltage distribution and frequent power outages in operational regions of communities and diverse enterprises. The system includes a power supply that converts 230V AC to 12V DC, a relay that uses a control pulse to alternate between connecting the battery to the LEDs and isolating it, and a rechargeable Li-ion battery that supplies power to the LEDs during blackouts. The parallel-connected LEDs light up during a power outage in the circuits. The circuit architecture shown here serves to mitigate the entire discharge of the battery, hence enhancing the battery's longevity. Key components of the system include a step-down transformer, a bridge circuit to convert AC to DC, a Zener diode to maintain voltage stability, capacitors for energy storage, and various diodes to control current flow. The project highlights the advantages of LED emergency lights, such as efficiency, longevity, and minimal energy waste, though it acknowledges the higher initial cost and temperature sensitivity as disadvantages. The automatic LED emergency light is suitable for use in homes, offices, retail shops, and other commercial settings. The project demonstrates a cost-effective and compact solution that enhances daily life by providing reliable lighting during power failures.
