INTRODUCTION

Motorised Laundry System

Nowadays, it is hard to keep track on the progress of our laundry that we kept on drying outside in the daylight. But, little did we know that the weather is not going to be sunny all the time because rains and heavy storm might come along in the way when we want to do our laundry.

Hence, we have created a Motorised Laundry System to prevent the laundry from getting ruined by the rain when we cannot collect it because of the weather is raining heavily or so. Besides, it eases our burden of having to carry the laundry there and then by just simplifying it with a single switch to do all the work for us.

The system works by pressing the switch to move the laundry outside and pressing it again to move the laundry back inside the area where there is a roof covering the laundry from rains.

This is a simple project from us using a PIC16F877A .This tools function when the user presses a button and dc motor serves to pull the clothes into the home area covered by the aid of the conveyor belt.This will make the user ease when the rain come and we just push the button to pull the clothes into the home area.
