Introduction: Arduino 4 Leg Robot Control Via Bluetooth

lets make a 4 leg robot with arduino.

Step 1: Parts :-


4x servo motors

2x 9v battering

Arduino uno

Bluetooth module

Some wires


Bluetooth app (you can download from here - Codes and app )

Arduino IDE

Step 2: Making It

  1. attach the servo motors to the plastic plate
  2. Connect all servo motor " - " to the 9v battery1 "-"
  3. Connect all servo motor " + " to the 9v battery "+"
  4. Conect 9v battery1 " - " gnd to arduino gnd " - "
  5. Connect other lines to the arduino pins according to the schematics image
  6. use 9v battery2 to power the arduino board

Step 3: Coding

Upload this Code to arduino..

Before upload the code remove the bluetooth module from arduino.

Step 4: App and Controling Robot
