- 8. ARDUINO “IDE” Integrated DevelopmentEnvironment The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. This software can be used with any Arduino board.

- 12. Why ARDUINO ? Itis an open-source project, software/hardware is extremely accessible and very flexible to be customized and extended. It is flexible, offers a variety of digital and analog inputs, serial interface and digital and PWM outputs. It is easy to use, connects to computer via USB and communicates using standard serial protocol. Lots of source code is already available and we can share and post our examples for others to use, too!
- 13. CAMERA MODULE Camera moduleused here is a OmniVision OV7670. Module has an onboard CMOS sensor designed for mobile application OV7670 camera is the affordable image acquisition module for embedded applications. This module talks over a modified I2C protocol that is known as SCCB (Serial Camera Control Bus).
