The story began when I visited the park last week and saw the boring Amusement in the dark, so I had an idea to add some fun by lighting it.
Idea:
the idea was to use (H01R0x) modules, the modules will work one by one in clockwise or anticlockwise direction.
the direction of lighting is controlled by a button.
Tools:
- Hexabitz RGB LED module (H01R0x)
1 / 2
Steps:
1. planning the array and assembling the hardware, connecting LED modules (H01R0x) in circular form, then we began in writing code.
2. Explain code:
- we defined fixed topology in all modules, it describes the connection of the modules between them, then we defined two private variables ID and button.
- in main.c file:
we gave the module in the middle a constant lighting and possibility of exchanging the messages with module number three which is connected with the button.
- According to the state of the button the direction of lighting is changed.
Code:
