Build a 4 DOF Robotic Arm with Arduino | Servo + Joystick Control

🦾 Welcome back to Lee Curiosity!

In this tutorial, I’ll show you how to build a *4 DOF robotic arm* using Arduino Uno R3, four servo motors, and two joysticks.

If you're new to electronics or robotics, this is a great project to learn how to control servos using analog inputs. A joystick is basically two potentiometers — when you move it, the corresponding servo rotates based on the input value. Simple and powerful!

Building this robotic arm will help you practice:
Controlling multiple servos
Reading joystick values
Wiring and assembling mechanical parts
Programming smooth and responsive movement
