IR Transmitter Circuit Using 555

Hi, friends, Today I am going to describe the working of Simple IR Tx circuit using 555 IC. You also know about this is called as timer IC. It is used here in astable mode. 

In this circuit IR LED is used to generate a frequency of 38kHz which is received by IR Rx Circuit to generate a high pulse.

 And you use this high output of the IR Rx circuit to operate devices connected to microcontroller.
