LIRC receiver

Posted on Feb 6, 2014

The description of this circuit is rather simple. The RTS line of the serial port gives power to the voltage regulator which fixes it to 5 stable volts. A diode is there to protect the serial port from inverse current. The capacitor helps to keep a stable voltage; all the grounds are bound to the GND line of the serial port. The data output of the
