A simple project to display real-time clock data on an I2C 16x2 LCD using an Arduino and DS3231 RTC module. Displays time and date in real-time. Uses I2C communication for both RTC and LCD. Easy to ...

Implementing this helper function allows easy code sharing with other development environments. As an example, any I2C code that uses this function can also work with STM32CubeIDE programs.

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Discover a 3D-printed DIY 7 Segment Clock powered by Arduino Uno, stepper motors and a DS3231 RTC module. Designed for tabletop use, it features precise mechanical movement and digital control, making ...
