TV remote controls work in a similar way but using a type of light called infrared (or IR for short). The remote control has an LED light in it which flashes really quickly to emit a message which is then picked up by the TV. The remote is called the transmitter, and the TV is called the receiver.

have you ever had older parents or relatives tell you about how much rougher their lives were back in the "good ol' days"? You may have heard apocryphal stories of having to walk to and from school…uphill…both ways…in a foot of snow!

Before you dismiss these stories as nothing more than old wives' tales, take a moment to consider that life a few decades ago might indeed have been more difficult than it is today. For example, decades ago your older parents and relatives couldn't simply "Google" the answer to any question they might have.

Instead, they had to do research with real books! Can you imagine? If that amazes you, you'll be really surprised by how different it was to watch television. In addition to having only a dozen channels rather than hundreds, they also had to walk across the room to turn a knob on the television set if they wanted to change channels!

Today, all you need to do is push a button on the remote control to flip back and forth between hundreds of channels. In fact, many of the things you use every day can probably be controlled remotely. From garage door openers and toy cars to lights and stereo equipment, it's easier than ever to control things from a distance.

How does all this remote control technology work? Is it magic? Nope! It's science applied to technology to make our lives easier and more convenient.

Remote control has actually been around a long time. In both World War I and World War II, radio-frequency devices were used to control boats and explosive devices remotely. Eventually, scientists would figure out how to incorporate that technology into all sorts of electronic devices.

Today, remote control devices are usually based upon one of two main types of technology: infrared (IR) technology or radio frequency (RF) technology. Let's look at how these types of technology help you control devices from afar.

One example of remote-control codes is the Sony Control-S protocol, which is used for Sony TVs and includes the following 7-bit binary commands (source: ARRLWeb):

Button 1 = 000 0000

Button 2 = 000 0001

Button 3 = 000 0010

Button 4 = 000 0011

Channel Up = 001 0001

Channel Down = 001 0001

Power On = 001 0101

Power Off = 010 1111

Volume Up = 001 0010

Volume Down = 001 0011
