This digital clock mainly uses the arduino nano board to read the time of the DS3231 clock module, and then controls the OLED display the real time.
When the time reaches the set reminder time, the buzzer will automatically sound. The clock can also monitor the real-time temperature of the system, and the time can also be adjusted manually.
Real Time Clock Module:
-Working voltage: 3.3–5.5V
-Clock chip: High-precision clock chip DS3231
-Programmable square wave output
-Memory chip: AT24C32 (storage capacity 32K)
-IIC bus interface, the maximum transmission speed is 400KHz (when the working voltage is 5V)
Micro SD Mini TF Card Adater Reader Module:
-Compatible: Micro SD card (≤2G), Micro SDHC card (≤32G)

【DIY Digital Clock Kit】You’ll be able to use this kit to build a real time clock and timing alarm clock the use of Arduino DS3231RTC and SSD1306 OLED. The little component are all included, such as breadboard, jumper wires, active buzzer, and switch button, with which You’ll be able to get began immediately.
【Clock Module 】The DS3231RTC is used as a real time clock chip which assists in keeping the time running even though the main power supply is off (coin battery is not included).
【Micro SD Card Module】Easy and cost-effective expansion of your Arduino storage space by means of this SD card module. The SD card module interface is a standard SPI interface. Easy communication with the Arduino SPI protocol.
【LCD 128X64 display Module】With high resolution of 128 x 64 pixels, the built-in standard driver chip SSD 1306 already exists in the libraries of Arduino, Raspberry Pi and 51 Series,which makes programming very easy.
【Reliable Technical Strengthen】We have prepared a detailed tutorial for this kit, all necessary files such as the software and a few code examples. You’ll be able to contact us on Amazon to get the PDF or downloaded from this link: https://github.com/WayinTop/Arduino-Real-Time-Clock-Kit-Tutorial
