i want to know how can i do this ?
Incrementally. Decide exactly what you want your project to do. Identify the sensors and actuators it will need to do it. Design the control algorithm which will define what the project does based on the sensor inputs. Discover how to connect those sensors and actuators to the Arduino, and how to control and manage them from the Arduino software. Add the code to implement your control algorithm. Test. Fix. Repeat until it works well enough.
