Binary Blink - Grasshopper troubleshoot

Hi, I’m a beginner at Grasshopper and I’m having an issue getting the binary blink to work on my LED,
it lights up with the Toggle switch without the binary blink, but when I include the blink and blink pattern it stops working, as you can see in the screenshots. Not sure what I’m doing wrong, any help would be much appreciated.


Your program should work! Is it Firefly 32 or 64 bits?
Can you post your GH file?

Hi @paco-paco,

Thanks for your reply, its firefly 64bit

see GH file
LED (10.1 KB)

It’s curious, your file work with my arduino!
Perhaps arduino code (firefly firmata) is not good in your arduino!
