Interfacing the RTC Module with Raspberry Pi Pico In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information. Since the screen is small, we will write smart code that changes what is shown on the screen. For a few seconds, it will display the time and date, and then switch to show the temperature.… |
