The DS3231 RTC module operates at 3.3V. It's essential to use a level shifter or voltage divider if you're using a 5V Arduino to interface with the 3.3V DS3231 module. This is a basic example of ...

Learn how to create a simple clock, using RTC and an OLED screen to display the time. In this tutorial, we will learn how to create a simple RTC (Real Time Clock) with the MKR Zero board. We will be ...

Macetech’s ChronoDot is a Real Time Clock module for projects requiring highly accurate time keeping and measurement. The ChronoDot uses the DS3231 chip, which features a TCXO to compensate f… ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

– Newt hardware is compatible with open-source Arduino libraries for ESP32-S2, Adafruit GFX (fonts), Adafruit Sharp Memory Display (display writing), and RTC RV-3028-C7 (RTC) ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...
