Arduino DCF77 library The DCF77 library adds the ability to read and decode the atomic time broadcasted by the DCF77 radiostation. It has been designed to work in conjunction with the Arduino Time ...

This Arduino code decodes the DCF77-signal without the use of interrupts. The DCF77 signal is broadcasted at 77kHz and can be received with a simple cheap receiver that cost €10. A one second signal ...

If you have already studied the circuit diagram, you will have noticed that the speaker is connected to 2 PWM pins of the Arduino. Here is a statement from the author of the Talkie.h library: >> On ...

[Brett] just completed his DCF77 Master Bracket Clock, intended to be a backup to an old logic controlled clock he made. For our readers that don’t know, DCF77 is a German longwave time signal whose ...

Measure: Frequency + Period + Pulse + Pulse/period + Capacity + Event counting. Bonus: decode DCF77 pulses and show date and time. The DCF77 pulses are also used to calibrate the system clock.

Ouah! (Wow!) No, this is not a project to imitate a dog's bark. Ouah! is in French, the ironic acronym for “Oh, Une Autre Horloge!” ("Wow, another clock!") Ouah! is a clock that decodes the DCF77 ...

[Brett] was looking for a way to improve on an old binary clock project from 1996. His original clock used green LEDs to denote between a one or a zero. If the LED was lit up, that indicated a one.
