Welcome to the forum @noobmaster

I think it unlikely that anyone here is going to complete your final year project for you. However, if you add debug nodes to the flow at appropriate places and work out exactly which node is not doing what you think it should, and post just that node and maybe a few around it, tell us what is going into the node and out of it and what is not as it should be then I am sure someone will help.

Ehh, was it your examination??

6

yes....bit in a rush

7

ok ...a function that can control a servo to open wait few seconds the close...will be helpfull

8

Have you looked at the delay node?

9

Use a trigger node for that. Set it to send the open command, then Wait the appropriate time, then send the close command.

11

Feed the button into the trigger node, when you press the button it will open and then close.
