In this paper, a wireless power transmission (WPT) using resonant magnetic coupling for mobile phone charger is presented. Solar energy was used as the energy source to address the scarcity of non-renewable energy sources and tackles the constraints of wired charging technology such as lack of universal electrical standard, untidiness and inconvenience of wires and wires' wear and tear. The system includes PV panels and battery, oscillator, transmitting coil and receiving coil and rectifier. Proteus 8.1 was used to simulate before implementing in the hardware. The resonant magnetic coupling resonated at 800 kHz ± 10 kHz. The maximum distance to charge a mobile phone was 4 cm at 3.7 V. All the objectives are achieved within the limited time frame. The significance of the project can help to eradicate the use of wires and the need of power plugs. The
future research includes the study of efficiency, coil design, system with multiple loads.

s that incorporates the ATmega328P microcontroller for precise control of two servo motors. The primary objective is to enhance the energy efficiency of solar photovoltaic systems by optimizing the orientation of solar panels to track the sun's movement across both horizontal and vertical axes. The ATmega328P microcontroller serves as the central control unit, receiving real-time data from sun position sensors. By utilizing this data, the microcontroller calculates the optimal angles for the solar panels to maximize their exposure to sunlight throughout the day. The servo motors are responsible for executing these calculated movements, ensuring that the panels are constantly aligned with the sun. The research focuses on the detailed design and construction process of the Dual Axis Solar Tracker System, including the integration of the ATmega328P microcontroller. Performance evaluation includes tracking accuracy, energy yield, and cost-effectiveness. The findings demonstrate that this innovative solar tracking solution significantly enhances the energy capture capabilities of solar installations, making it a promising technology for improving the sustainability and efficiency of renewable energy systems in various applications.
