I would like to do the following:
1] When I power up my wooden automaton [powered by 110v AC] I would like that sensed then
2] Send a signal to trigger to a Wav or MP3 Board to play a stored music file.
How can I do this? What Arduino hardware is reqd?
Simplest/safest, IMO would be to wire in a mains relay and use the contacts to provide an input to your Arduino.
You could also monitor a 5 VDC wallwart on an input to the Arduino.
There are "green" energy savings power boards available.
One master socket and 3 or 4 slave sockets.
When the master user is turned on, the slaves are turned on.
A slave socket could power your Mp3 player.

Did any of the previous answers solve your inquiry, or are you specifically wanting to sense CURRENT draw (not just available voltage)?

you mean like, we did not even bother to address your question, we just posted things we like ?
I just want to be able to have the 'wav' board trigger when am automaton model starts running. It seems that sensing voltage is probably easier to do than current sensing.
I am a COMPLETE newbie to Arduino so really need more assistance.
The type of boards I would need to get a] Voltage sensor; b] main Arduino board itself; c] the wav board to play the wav file.
would appreciate all the help I can get.
Thanks for the reply so far. did not reply earlier as computer was down
