This Miniscule IR to HID Keyboard Hides in a Key Cap
Shards of silicon these days, they’re systematically taking what used to be rather complicated and making it dead simple in terms of both hardware and software. Take, for instance, this IR to HID Keyboard module. Plug it into a USB port, point your remote control at it, and you’re sending keyboard commands from across the room.
To do this cheaply and with a small footprint used to be the territory of bit-banging software hacks like V-USB, but recently the low-cost lines of microcontrollers that are anything but low-end have started speaking USB in hardware. It’s a brave new world.
