Thanks Barragan,
I'm waiting for the site update,

but now i have to connect a 6v Dc solenoid
I understand a solenoid is an electronic coil with a magnet in it ...
basically.
I was reading the forum ,and i found this :
http://wiring.org.co/cgi-bin/yabb/YaBB.pl?num=1147904339
and from there i tried going here:
http://wiring.org.co/reference/electronics/coil.html
but my browser kept saying 404 not found
should I connect in to an h-bridge or straight to wiring

?
what is the circuit ?
and also when you want to power
the wiring ,were can you get batteries, that are
connectible to the"external power supply connector'.
and I read in the hardware section that you can also
power wiring by a regulated 5 volts and you connect it to and you connect it to any vcc pin?
thanks,
John
