WayinTop Real Time Clock Kit with Tutorial for Arduino, Clock Module + Micro SD Card Driver + Nano V3.0 Development Board + OLED 128X64 Display + Buzzer + Breadboard Jumper Wires

This digital clock mainly uses the 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 be adjusted manually.
