Project: Arduino Robotic Arm

This project features an Arduino Uno programmed to control servo motors that serve as the joints of a robotic arm. The setup can also be modified to resemble a robotic crane with a few simple tweaks.

The Arduino Robotic Arm is controlled via four potentiometers, each corresponding to one servo motor. By rotating these potentiometers, you can manipulate the servos to pick up objects. With practice, users can efficiently transport objects from one location to another.

🌟🌟Key Features:

• Control: Each servo is independently controlled by a potentiometer, allowing for precise movements.
• Versatility: The arm can be adapted to function as a crane, providing additional utility.
• Scalability: While the current setup uses low-torque servos, more powerful servos can be integrated to handle heavier objects.

🌟🌟Applications:

This robotic arm is not only a great learning tool for understanding servo control and robotics but also serves as a foundational project that can be expanded upon for more complex robotic systems.
