Hi there,

I'm almost a newbie, so be patiente with me, ok?
I'm working on an infrared device to avoid my 'bot' colision. I'm using a Vishay TSOP1240 as a receiver, and a LM556 to generate 40Khz pulses.
The project has a size constraint and I was wondering if it is feasible to use a PIC12F675 with INTOSC to generate pulses of 40 Khz and perhaps increment some protocol to distinguish between external noise and my pulse.
