Description
Presenting the Single Axis Solar Tracker with USB Mobile Charging – a fully assembled and tested engineering project by Mechanic37. This smart solar system uses dual LDR sensors and an Arduino Uno to intelligently track the sunlight and rotate the solar panel for maximum efficiency. The energy is stored in two 18650 Li-ion batteries and can be used to charge mobile devices via the built-in USB output.
The tracker is neatly mounted on an MDF or acrylic base, with all components pre-connected: TP4056 charging module, step-up/step-down converter, voltmeter display, and toggle switches for power and charging control. No need to assemble or solder – just plug and play. Ideal for engineering and school students for exhibitions, practicals, or renewable energy demonstrations.
Whether you’re a student, teacher, or DIY enthusiast, this project offers hands-on understanding of solar tracking, battery management, and Arduino automation. A detailed PDF report with working explanation, circuit diagram, and Arduino code is included.
⚠️ Note: This is a ready-to-use project, not a DIY kit.
