The current project is for a 1-inch digital tube. Click here to go to the 3-inch large-screen version project.

Warm reminder: It is recommended to choose a 0.8mm thick PCB. If it is thicker, the DC holder will be pushed up, causing the shell to tilt up, which is very unsightly.

Function

1. Light control function: the brightness of the digital tube changes with changes in external brightness
2. Temperature and humidity detection function: You can view real-time temperature and humidity and historical temperature and humidity on the Blinker APP
3. The first digit does not display "0" function: When the first digit of the digital tube is "0", it is not displayed by default (for example: when it is eight o'clock in the morning, only "8:00" is displayed instead of "08:00"
4. Alarm clock function: Please see video 2 for the setting method. Press the button to turn it off, or wait for it to sound a certain number of times to automatically turn off (the alarmCountMax variable can be changed in the program, the default is 30)
5. Mobile phone network distribution function: see here for details (not included in the main program, but in the attachment, you can paste it into the main program by yourself)
6. RTC real-time clock function: RTC time is usually used, and NTP time is updated once a day to ensure accuracy and not occupy too much NTP server resources.
7. Digital tube automatic switching function: displays year, month, day, temperature and humidity every two minutes. Functions such as countdown to high school and college entrance examinations will be added in the future. It is recommended to collect it.

The network distribution function has been packaged in the attachment. If you need to add the network distribution function, you can paste the routine into the main program by yourself.
