Bluetooth Wireless Robot Car Controller

This project presents a robot car controller that utilizes a Bluetooth wireless controller, allowing users to control the small robot car using a smartphone and an Android app. The system consists of an Arduino microcontroller (ATMEGA328), an HC-05 Bluetooth module, two BD6211 H-Bridge motor drivers, and an onboard DC-DC converter that provides 5V power to the microcontroller and related circuitry. The circuit operates on a 6V DC battery, making it an ideal choice for small to medium-sized tank and robot car applications. Each H-Bridge channel can handle currents up to 1A.
