This report describes the design and implementation of a wireless smartphone charging system controlled by an Arduino microcontroller. Power is transferred inductively from a transmitter coil (charging pad) to a receiver coil mounted on or inside the smartphone. The receiver measures battery percentage and charging status, sends that information via Bluetooth (HC-05) to an Android application, and the Arduino receives control/status data from the HC-05 module. Based on battery percentage, the system lights red/yellow/green LEDs to indicate low, medium and high charge levels. An I2C LCD displays real-time charging status and battery percentage. When battery percentage reaches 95%, a relay module is triggered to disconnect the transmitter, preventing overcharging and improving battery longevity. The report covers objectives, literature survey, hardware and software requirements, implementation details, modules, testing, advantages, limitations, conclusion, and references.
