Introduction: IR Blaster (LIRC)
In this Infared Blaster setup we will utilize the TSOP4838 IR Receiver to record IR remote codes in order to play back the commands using an IR LED and a BC547 transistor. Then utilizing python we can create a script to automate the transmission of commands, i.e. turning on a TV set and changing the input source automatically.
