A modern person hardly thinks much about how technology makes his life easier, and after all, not only technology itself contributes to this, but also objects that help us to manage it. But even some 60-70 years ago, life was completely different and these objects were only being developed to now actually be our life companions. Remote controls have a valuable history behind them, the first prototype of a modern remote control, which are presented at www.pulti.ua , was created back in 1950 and was a box connected to a TV with a cable. Further, the principles of work began to improve, remotes appeared based on sending a beam of light in the direction of a photocell, piercing ultrasonic signals were used, there was even a case when a toy xylophone could switch channels on TVs.
Like all technology, remote controls for comfortable use have evolved to the point that infrared communication was developed. The principle of its operation made life much easier, and now you do not need to direct the remote control exactly at the receiver or listen to an unpleasant noise. The remote control is used for a TV, computer, DVD player, satellite receiver, sound amplifier and other equipment, but if you think so, let's say for a home theater you need to turn on five or six remotes in sequence. It's not very convenient. To solve this problem, they came up with universal remote controls with programmable control. There are some models where there is a function of adding to the list of available devices various new models or brands of household appliances that were not originally supported by this remote control.
Currently, there is a wide range of remote control choices to your taste, but do not forget that, like many other household appliances, multifunctionality is not always good and universal remotes will not be a full replacement for the original remote control! It even happens that with virtually complete compatibility of the remote control and the model of the device, some functions may be confused or completely absent. And to check the functionality of the remote control there is a very simple method: you should see the infrared signal transmitted by the remote control using a video camera of any mobile device.
