If you post your current project,
We can then help you further.
You also need to state what version of flowcode you are using.

Hi,

Better to attach your chart to the message (Full Editor & preview -> Attachments (below edit window) -> Add files) or drag and drop the file!

There are many ways to do this - I did a very simple demo - that uses an array of LEDs and using consecutive pins (select port mode in properties or set the individual pins)
So - I use the fact that to light the relevant LEDs I can write 2^n-1 to the port (so 0 leds -> 0, 1->1 2->0b11, 3->0b111, and 4->0b1111)

Hello.
I have edited your post as caps is seen as shounting .
Please don't do that again.
The issue with your project is you used decision branches with negative values e.g If:count >= -2
Count variable is a byte = 0 to 255, so it will never be a negative value.
Therefore all the decision branches with negative values to compare will always be false.
I have modified your project.
