1389510A+Simple Clock 02

  
     60 three-primary color LED lamp beads integrated with the WS2812 chip are used as dial indications, using different colors to represent the hours, minutes and seconds of the clock, and automatically adjusting the clock brightness according to the intensity of ambient light. The STC 8-pin microcontroller is used as the main control, and a time chip is used as the system travel time. At the same time, the existing China Mobile M5311 NB-IOT module is integrated as the system automatic time correction source. In the future, you can also consider using OPEN CPU mode and directly use M5311 as the main control chip.
    The reason for doing this project is that the WS2812-like three-color LED light strip with silk screen printing of CX1611 was previously controlled by an STC15F104E 8-pin MCU. The video shows the effect of the light strip simulating a clock. The red light represents the hour, the blue light represents the minute, and the green light represents the minute. The lights indicate seconds. The finished clock-like display is 3 meters long. Although it is very beautiful, it is still too large.
    Just in time for Jialichuang's color screen printing public beta, I just wanted to make such a small decoration.
