- A first improvement can be to simplify the assembler program to have a more performant program. The program already works but it could work faster if we delete some parts (this will make the program more difficult to understand for a third party but the display will be more fluent).
- It's possible to make a program without using the interrupts (it will be easier and faster).
- You could also build around the tower a wooden structure for example and fix it more harder (if you want to use it in a disco, for example) because the tower is rather fragile. You can also incorporated the microcontroller in this wooden structure to make it transportable.
