Robotic Arm

The main component for this robotic arm is the ESP8266 WiFi module. ESP8266-12
This module measures only about 1" x 1/2".
The entire robotic arm controller, web server and WiFi access point are implemented on this module. In addition to learning how to program this module, there are four other components that you'll need to work with:

  1. Stepper motor for rotating the arm.
  2. Servo motor for raising and lowering the arm.
  3. Electric magnet for picking up the metal balls.
  4. RGB LED for visual effects.
