Project : Radio Controlled Clock with USB

Most widely spread DCF77 radio-controlled clock receiver are connected computer via the serial port but this electronic project will show you how to make DCF77 radio clock receiver connected via USB using a small 8-pin microcontroller ATtiny45. The project programed with the smart firmware called AVRUSB and AVR-CDC. With this firmware combination, the DCF77 receiver creates a serial port and is fully compatible to old-style true-serial-port ones. No software adaption is necessary.
