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.
