Hello, i have a problem with flow that controls servo motor via twitter node.
When i receive tweet with given keyword the servo should go at 120 waits 5s. and goes to 0.
The problem is that i receive error in my debug node and servo doesn't move. The servo is attached to gpio 17 of raspberry pi.
this is the flow:
