2. Control requirements: Ⅰ 34 1 212345678 Ⅳ 56789 (1) The turn-on and turn-off sequence of the eight lights in the middle of the advertising screen is:1light on →→→→→→→
The eighth root is opened at the interval of1s. When it is fully opened, 10s will be displayed, and then it will be closed at the interval of 1s from 8 to 7 to1,and then it will be closed for 2s after it is completely closed. Then light up from the eighth root, and light up 7 → 6 →→→→1and interval 1s in turn, and display 5s. Then it goes out from1→ 2 →→→ 8, with an interval of 1s, stops lighting for 2s after it is completely extinguished, and then runs repeatedly.
3. Twenty-four running water lamps are divided into six groups in groups of four, and the interval from I to II to VI is1s.
Move forward in turn, light every 1 when lighting, at the same time I "①, ③" goes out → III "⑨, ⑦" goes out, at the same time II "⑦, ⑦" goes out, so move for a period of time (for example, 30s), then move in the opposite direction for a period of time, and so on.
4. The system has single step/continuous control and start and stop buttons.
5. When starting, the lamp tube and running water lamp are started at the same time, and when closing, they can be closed at the same time or separately.
6. Applications requiring shift instructions
7. In the control requirements of 1, if it is required to change the display of 10s when it is fully lit to flash 5s at intervals of 0.5s at the same time, please try to modify the program.
