Radio remote Control for PDAs and Smartphones
On his website, under the title ‘AVR Blue Remote’, the author describes (in German) a Bluetooth-based remote control unit featuring six output relays and six sensor inputs. The site also includes Smartphone software (avrblueremote.exe) and microcontroller software (avrblueremote.hex). These can be used as the basis for projects such as a short-range (up to 10 m or so) remote garage door opener or a remote lighting controller. The software is free for use by private individuals.
