Dude... you realize your 'innovative' device has been done 1000+ times over & over & over again! And it has the same BS limitations ALL of them have.
1) You have no database. 500,000 is shit. There are millions of codes needed to even begin. And I'm wiling to bet top dollar, you have none of the 'special' codes that are needed for devices (just like all these other "me to" devices).
2) 38kHz only? You know how much this limits your device to controlling things in the REAL world.

By the way (in case you didn't notice), this is a professional forum section. Where we use REAL control systems that have been around for decades.

Also, did you pay or get permission from the forum owner to spam here?
