The TSOP 1738 is a member of IR remote control receiver series. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low.

GETTING STARTED VIDEO
This module, when given supply of 5V provides digital output from the op pin. In ideal state, the default value at the pin is 5V or digital 1 and whenever a 38 kHz IR signal strikes this module (from IR remote) its value at output pin drops to 0V or digital 0. Hence we can interface this module just like we are interfacing a push button with our board.
And hence, I’m attaching a video on Interfacing a push button with your arduino board. You can use this same code for interfacing TSOP with arduino, just attach op pin of TSOP at the pin of arduino, where push button is attached.
