IoT dot matrix clock

Write in front:

       At first, I saw hack’s clock on station B in November 2020, and thought it was very suitable for tossing around. Then I looked at similar solutions at that time and felt they were not very good, so I designed such a clock from scratch; I would like to pay tribute to this solution. The first designer of Hack Lab.

Features:

       1. Time and date display

           2. Temperature and humidity display (sensor GXHT30 accuracy 1%, Xiaomi temperature and humidity sensor equivalent)

           3. Alarm clock broadcast (development on demand, hardware support)

           4. Automatic brightness

           5. High-precision power-down timekeeping (equipped with a rechargeable button battery, so there is no need to worry about running out of power)

           6. Touch control (three touch buttons for manual control)

           7. APP control (connect to Blinkr platform to achieve remote control and remote meter reading)

           8. Custom functions (free custom boot animation, or page functions such as decimal point flashing/non-flashing)

           9. Automatic program download/OTA download (automatic download eliminates the trouble of pressing buttons, and OTA download allows the body to be updated wirelessly)

      The communication and data sharing group number is 523314319, which provides step-by-step assembly instructions. The software and hardware will be updated from time to time, so they are not included in the attachments. If necessary, you can join the group and get it from the group file.

         The file is designed using AD , and there will be some deviations when opening it with Lichuang EDA. If you need to make a board, it is recommended to directly use the .PcbDoc file without (ASCII) field in the group file .
