This Project Android Phone-controlled robot is constructed using 8051 microcontrollers and a Bluetooth module. The robot will be equipped with DC motors, and the commands received from the Android application will determine the direction of these motors. Furthermore, the status of the robot will be relayed back to the Android app. This project will serve as a valuable resource for interfacing the HC-05 Bluetooth module with 8051 microcontrollers. It is worth noting that we have previously utilized the Bluetooth module to control home appliances with 8051 microcontrollers, further enhancing our expertise in this area.
