With this kit, you'll wire three potentiometers to command each joint of a 3-degree-of-freedom servo arm. Twist a knob, and the corresponding shoulder, elbow, or wrist servo follows in real time. The SG90-based gripper opens and closes to pick up small objects, turning your desk into a tangible control station. No coding required for core motion—just plug, twist, and see the arm respond.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA functional 3-axis robotic arm that you control with analog knobs. The base rotates, the arm reaches, and the wrist tilts—each joint moving exactly to the angle set by its dedicated potentiometer.
