Robotic Arm and leg control using Potentiometer and Servo Motor

In this project, we are simulating the basic movements of a robot's arm and legs using Arduino UNO, 4 servo motors, and 4 potentiometers in Tinkercad. Each servo motor is controlled by one potentiometer, which acts like a manual control knob.

A robot needs joints to move its arms and legs. These joints are controlled by servo motors, which can rotate between 0 to 180 degrees. To control the angle of each servo, we use potentiometers — rotary knobs that provide variable voltage. As you turn the knob of a potentiometer, the connected servo motor rotates to a new position.Each potentiometer controls a specific servo motor:

Potentiometer 1 ➝ Servo 1 (Robot Shoulder Joint)

Potentiometer 2 ➝ Servo 2 (Robot Elbow Joint)

Potentiometer 3 ➝ Servo 3 (Robot Hip Joint)

Potentiometer 4 ➝ Servo 4 (Robot Knee Joint)

This setup mimics how a human moves their limbs — with different joints moving independently.The Arduino reads analog signals from each potentiometer (values between 0 to 1023).It maps these values to servo angles (0 to 180 degrees).Each servo then moves to the corresponding angle, simulating joint movement.
