The remote control has begun to occur to humans since 1893. At that time, an American citizen named Nikola Tesla drew the concept of remote control work. After being stored for a while, it was only in 1950, the picture of Nikola Tesla was successfully manifested into reality by an Austrian named Robert Adler.

After successfully tested, this tool was then produced on a large scale by a company called Zenith Radio Corp. At the beginning of its discovery, the remote controller still had to be connected using a thick cable that was connected to the television set.

It turns out that the thick cable is very troublesome because it often makes people fall tripping or often broken bitten by a dog. When the cable is off, this remote controller also does not work. Oh yeah, when first introduced to the market, this tool has not been called a remote controller, but lazy bone or literally means ‘lazy bone’.

In 1955 an engineer from Zenith, Eugene Polley, created a wired remote controller. The shape is similar to a hair dryer or hair dryer. The tool is called “Flash-Matic” and can direct the visible light to the photocell located at the corner of the television. These rays can activate four buttons on the television, including changing the display of the television screen, turning down the sound or changing television channels.

Unfortunately, the photocell on the television is less able to recognize which light comes from the remote and the light coming from other sources, so sometimes when exposed to room lights/sunlight, the channel or volume on the television can move by itself.

In 1956, Robert Adler developed a new remote control technology with ultrasonic waves (Space commands). When a user clicks on the button on this remote controller, this tool will automatically send high-frequency sounds that only the television recognizes. Another advantage, this tool does not need a battery. But this remote controller also has its disadvantages, namely, the channel or volume can move on its own if there is a frequency of other devices that are in line with the frequency on the television.

Then, starting in 1980, Zenit made a remote control experiment using infrared light. This remote control uses low-frequency light waves, so that the human eye cannot catch it, but can be caught on television. The discovery of remote controls using infrared light then managed to overcome the shortcomings of remote controls that use ultrasonic waves.

After that, the use of remote control has experienced rapid development. Not only for television sets, but this tool is also used to control other electronic devices such as air conditioning, radio, tape, and so on.
