IR software & hardware basics

[skimask]

Thanks a lot skimask, I'm gonna try an IR module.
I've seen on rentron's web site that he used a NAND. Going to check this out - didn't read this carefully enough. May I ask you over which distance you got good & reliable results? Dave, just saw your post. Yup, going for a module!!

Maybe I did use a NAND gate, don't remember at the moment...
Some people use gates, some people actually switch the PICs internal timer that generates the 38Khz on and off really fast.
