Project Idea:
This project enables controlling a robotic arm using an Android device through Bluetooth commands. The Bluetooth module receives signals sent from an Android app, and the 8051 microcontroller processes these commands to control the motors that move the robotic arm. Users can move the arm up, down, open or close the gripper, allowing it to pick, move, and place objects efficiently.
 
Project Description:
The system uses an AT89S52 microcontroller interfaced with an HC-05 Bluetooth module to receive wireless commands from an Android smartphone. These commands are interpreted by the microcontroller to drive DC motors attached to the robotic arm, which moves accordingly to perform tasks like gripping or releasing objects. The robotic arm can execute motions such as upward, downward, and gripping movements based on the app inputs, making it suitable for precise remote-controlled manipulation.
