INTRODUCTION

1.1 Background of the Study

The first remote control, called “lazy bones” was developed in 1950 by zenith Electronics Corporation (then known as zenith Radio Corporation). The device was developed quickly, and it was called “zenith space command”, the remote went into production in the fall of 1956, becoming the first practical wireless remote control device .org/wiki/ Remote control).

Remote control facilitates the operation of fan regulators around the home or office from a distance. It provides a system that is simple to understand and also to operate, a system that would be reliable and easy to maintain and durable irrespective of its usage. It adds more comfort to everyday living by removing the inconvenience of having to move around to operate a fan regulator (Howstuffworks, 2006).

Today, remote control is a standard on electronic products, including vicars, cable and satellite boxes, digital video disc players and home audio players. In the year 2000, more than 99 percent of all TV set and 100 percent of all VCR and DVD players sold are equipped with remote controls.

The average individual these days probably picks up a remote control at least once or twice a day.

Basically, a remote control works in the following manner, a button is pressed. This completes a specific connection which produces a code line signal specific to that button. The transistor amplifies the signal and sends it to the led which translates the signal into infrared light. The sensor on the appliance detects the infrared light and reacts appropriately.

The remote control’s function is to wait for the user to press a key and then translate that into infrared light signals that are received by the receiving appliance. The carrier frequency of such infrared signals is typically around 36 kHz (Forrest, 1986). Usually, the transmitter part is constructed so that the transmitter oscillator which drives the infrared transmitter LED can be turned on/off by applying a TTL (transistor-transistor logic) voltage on the modulation controlled input. On the receiver side, a photo transistor or photodiode takes up the signals.

1.2 Statement of the Problem

Fan is an unavoidable electrical appliance in our day to day life. While the basic fan has evolved very little, the methods of controlling its speed have changed vastly, from bulky regulators using resistances, to the present day miniature solid state regulators.

1.3 Objective of the Study

The main objective of this study is to design and construct a ceiling fan remote control.

1.4 Significance of the Study 

The results from the study of this study will be an additional knowledge to the existing literature on design and construct a ceiling fan remote control.

Since remote control facilitates the operation of fan controls around the home or office from a distance. It provides a system that is simple to understand and also to operate, a system that would be cheap and affordable, a reliable and easy to maintain system of remote control and durable system irrespective of usage. 

It will also add more comfort to everyday living by removing the inconvenience of having to move around to operate a fan control. The system seeks to develop a system that is cost effective while not under mining the need for efficiency.

1.5 Scope of the Study

This study concerns about design and construct a ceiling fan remote control use in every home in Nigeria and beyond.

1.6 Limitation of the Study

Scarcity of material the researcher has received very little attention from scholars on this area.  Consequently, there are few literary publication on the student; the researcher was therefore limited to reviewing few literature which are mostly in origin, through relevant to the study.
