HOW TO MAKE A MOBI CAM STAND WITH ARDUINO| CAM AND BT INTERFACE

This project is base on Arduino microcontroller. this video explain how to make a mobile camera stand using servos and drafter. we make a 4 leg camera stand which is controlled by Arduino using Bluetooth module and interface mobile cam with web browser using IP CAM software.

COMPONENT REQUIRED FOR PROJECT:
(1)- A drafter
(2)- two servo motors
(3)- Arduino pro mini microcontroller
(4)- Bluetooth HC05 module
(5)- bicycle spokes
(6)- bolt and screws

Software required for this project:

(1)- Arduino IDM
(2)- Proteus for circuit design
(3)- Bluetooth serial controller for android devices
(4)- IP CAM app for android

Arduino coding:
