The weirdness comes in when I start using my arduino uno to generate a signal (38khz + pulsed) that I will eventually drive an IR LED. But before I even attach the signal to a LED, I can get the receiver circuit to light up just by touching an exposed end of the wire hooked up the arduino's output pin. Fig. The IR LED is same aspect as the normal LED. /Subtype /Image ?���eAK����,ZR�p�pt��Q�%E � ����ӧ�(pzz��ſh���kud/��o���'O����ի���zPy���j������6���k�/R ��h���B���J�!o�K����|kU����_= 5) Test the circuit by bringing an arbitrary object near the IR sensor unit.
