What is Arduino®
Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a twitter message or publishing online. Surf to www.arduino.cc for more information
Product overview
- The Whadda RTC DS3231 module is a real-time clock that enables accurate timekeeping with minimum fuss. It uses a DS3231 IC, an extremely accurate RTC chip with a built-in 32 kHz crystal oscillator. The chip also features a basic temperature sensor and alarm clock capability.
- The RTC module uses a standard I²C interface and can easily be interfaced with various developments boards (such as an Arduino® compatible board).
Specifications
- Supply voltage: 3,3 – 5 V DC
- RTC IC: DS3231
- RTC accuracy: ± 2 ppm (from 0 °C to +40 °C)
- Temperature sensor accuracy: ± 3 °C
- Maximum I²C bus frequency : 400 kHz
- Backup battery: CR2032
- Dimensions (W x L x H): 43,2 x 22,4 x 14,7 mm

Example program
You can download the example Arduino® program by going to the official Whadda github page: github.com/WhaddaMakers/RTC-DS3231-module
- Click the “Download ZIP” link in the “Code” menu:
- Unzip the downloaded file, and browse to the set_time folder. Open the example Arduino® sketch (set_time.ino) located in the folder.
- Use the Arduino Library manager to install the DS3231 library, by going to Sketch > Include Library > Manage Libraries… , typing in DS3231 in the search bar and clicking “Install”:
- Connect your Arduino compatible board, make sure the correct Board and connection port are set in the tools menu, and hit Upload
- Open the serial monitor by clicking the serial monitor button , make sure the baudrate is set at 9600 baud
- Follow the on-screen instructions to program the current time into the RTC module
- Now open the display_time example, and hit Upload
- Open the serial monitor by clicking the serial monitor button , make sure the baudrate is set at 9600 baud. The current time and temperature will be printed out in the serial monitor.
