i hope someone can help me out here, i would like some help here anyone.
i want to build an infrared transmitter/receiver system to connect to my pc through the USB port. The Infrared transmitter/receiver device will act as a sensor system to detect any movements made at the doorway and send a signal to the pc, and the pc will alert me via an SMS.
So far i have the SMS part working, i would like to know what is needed to get such a signal to the pc via the USB and probably what is necessary for me to write drivers for this device.
However i have not much experience in the hardware aspect of computers.
Thanks in Advance.
