Abstract: The DCF77 signal is used to carry out the information of precise time for long distances. Standard DCF77 receivers consist of AM long wave receiver circuit, connected to a data processing ...

Radio-controlled clocks can automatically adjust the time and calendar by receiving standard radio waves. However, radio-controlled clocks do not always receive radio waves, and depending on the ...

DCF77 is a radio signal is a 77.5 kHz frequency that is reduced from 100% to 25% to create the protocol. This signal is very accurate sending the legal time of Germany CET or CEST and is emitted ...

Today, reception conditions for radio-controlled clocks are often very difficult. The widespread switching power supplies, LED-lighting, TV-sets and scattering DSL signals create an interference fog ...

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 ...

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 ...
