Arduino Bluetooth Controlled Robot Car (4WD)

Overview

• This Arduino-based Bluetooth-controlled robot car is designed for wireless mobile navigation and remote handling. Built on a custom white 4WD chassis, the car interfaces directly with a smartphone or tablet to receive directional commands in real time. Core Functionality: o Wireless Control: Connects to a companion mobile app via Bluetooth, allowing the user to steer, drive, and control the vehicle's speed remotely. o Power & Drive: Equipped with four high-torque TT gear motors regulated by a robust L293D dual H-bridge motor driver for reliable multi-directional movement. o Proximity Sensing: Integrates ultrasonic sensor components for proximity measurement and obstacle monitoring. o Rechargeable Battery System: Features a centrally mounted high-capacity Lithium-Ion battery 3S 12V pack with a physical on/off switch and an easily accessible external charging port for streamlined power management. Package Includes: o Fully assembled and wired 4WD Bluetooth Robot Car o Comprehensive documentation, including schematic diagrams and mobile application setup instructions.
