Wordclock with an Arduino ESP32 Nano. Built your own word clock with one or four languages with an Arduino ESP32 Nano. You can control it with your phone of with a web page. Software updates can be uploaded with OTA (Over the Air). It will keep its time within the second correct with the internet NTP time and a time zone selection.

DCF-77 receiver 433Mhz transmitter with ATTINY85
A clock using a DCF77-signal decoder algorithm not using interrupts. The received bits are made visible with other info about the signal. The time is send into the ether with a HC12 transceiver.
A HC-12 time transmitter with DCF77 time receiver
This Arduino code decodes the DCF77 signal without the use of interrupts.
