I cant find it...

Im pretty sure this is already on here but I cant seem to find it.
What I wanna do is have a wireless pc in my inventory and be able to send a signal to one of my computers so I can turn a machine on or of. I need to be able to control it with the pocket version cuz I wanna have other people have the same(or other ) control over machines, doors, power system etc.

Redirect me if i missed something, but I couldnt find it…

You haven't actually explained the bit where you got stuck, but it sounds like you may be after this?:

I control multiple turtles this way for tandem mining efforts.
Here's an example of what I use:

On the turtle:

On the pocket computer:

local programParam = { ... }
rednet.open("back")
rednet.broadcast(programParam[1], "startComb")

To execute on the pocket computer, I just type "startComb xx" where xx is a number.
I would guess that with the link to the rednet.api and that example code you can probably get things going!

finally my account shows me my posts that was kinda weird…

I figured I could run a receive program on the computer and when it recieves a certain string it executes the program I want it to.
At least that worked for me
