This example describes how to use the datetime and ds-rtc libraries, format date and time values, and work with real-time clock (RTC) modules for Arduino. Upon the completion of this guide, you will learn how to create a simple digital clock based on a DS1307 I2C RTC module and I2C LCD display.
This is a modified library of digital clocks for LCD 1602 with support for Russian characters. The original project from XOD "Digital Clock Example — Working with RTC Modules" was taken as a basis. If you wish, you can contact me via Google mail.
The following library is used for work with dimmer, it gives ability to control large ammoun of dimmer. This lib used with Leonardo, Mega, UNO, ESP8266, ESP32, Arduino M0, Arduino Zero, Arduino Due, STM32.
As long as the board is supported by XOD
