Hi - I'm an absolute newbie - apologies if I have mis-posted or this is in the wrong place!!
I need to be build an IR circuit (if that is the best option) to detect when a user approaches a kiosk - as we want to change what appears on the kiosk screen when a person comes to use it (which will primarily be indoors). Consequently, I will need to take the output from the circuit and make it available to our processor - we currently have the option to use Android, Linux or Windows - and therefore assume I would need the appropriate drivers.
If anyone can provide me with some feedback or point me in the right direction for hardware and software, I would be very grateful.
