Controller : Arduino Uno

https://ejctraining.wordpress.com/201...

The project generally relates to an automatic opening and closing of door which will sense person or object approaching door and open automatically. This system is controlled by Arduino micro controller. The system includes DC motor which makes door to slides during opening or closing by rack and pinion gearing, a LCD to display information state of door, an audio buzzer to make sound through the duration of opened door and a controller for controlling the opening and closing of the door as a person or object detected by sensor.
The whole system is mechatronic system which is designed using seven steps of mechatronic system design. These steps are as follows: The need, Analysis of the problem, Preparation of specification, Generation of possible solutions, Selection of possible solution, Production of detailed design and Production of working drawings. Specifications of all parts of the system in discussed in detail in the report.
Finally the system is executed by making prototype of the system which is demonstrated at the time of submission.
