What is simpler, to use ethernet connection or wifi?
Should I / Can I use it as a server or is better to use local web server for the site and the device just as external interface?
What shall I use as storage, Arduino, clearly has not enough memory;
shall I use an SD card or other kind of external memory? How much memory would I need for <10 remote controls?
Is there any arduino library that I shall familiarize myself with?
I really do not know how much space do the codes use, I presumed that Arduino memory is not enough. For a few codes for test purposes it surely will be enough, but I intend to add to it all the remotes for the devices that I have now and for any that may come. So, I would like some external memory that would not be a limiting factor in the future. I understand from power7net's project that codes are small and that there is enough space for ca. 10-15 different codes on Arduino itself. If I come to working prototype, I'll then go for external memory, wifi and local server in second prototype. I'll will surely find informations about these topics on the forum or somewhere else on the web. If I come to some problem I'll ask here.
