Once we convert the infrared signal into data, we can easily process that data and perform any conditional task as per our wish. Then arduino will analyze the received signal and convert it into hex data.

The infrared receiver will receive the signal from remote and give it to arduino. ARDUINO and TSOP 1738 will do that for us. In this way we can convert the signal pattern into data. Our aim is to identify the high and low signals as 1 and 0. So whenever we press a particular button we get a particular signal pattern which is assigned to that button only. Each of the button has its own unique pattern. We can call this bunch of ON and OFF as a signal pattern. This signal has a bunch of ON and OFF or you can say HIGH and LOW. However we cannot see this light with bare eyes.

means the remote is emitting infrared signal whenever I pressed the button. An IR LED (infrared light emitting diode) is a solid state lighting (SSL) device that emits light in the infrared range of the electromagnetic radiation spectrum.
