The DCF77 signal is a puls-signal with AM modulation with carrier frequency 77.5kHz. It has a small bandwidth. The carries include time and date information and will be transmitted in a simple binary-coded format by on-off modulation of the carriers. (100ms/200ms) The Signal time and date code include the following information: year, month, …

The LDR Sensor also know as the Photo-resistor is basically a simple sensor that its resistance value changes with light. (resistance will lower with more light.) The LDR isn’t very precise, so you can not get a LUX reading but it is good enough to tell the difference between light and shadow. It …
