Hi all,

I've undertaken a project to connect an arduino to a mains powered machine that utilises a wired remote control.

Now I have found a tutorial that explains how to do it http://www.instructables.com/id/Motion-Triggered-Fog-Machine/step2/Schematic/ however I'm just wondering if this could be achieved using the breadboard or would it be better to do it on the copper clad PerfBoard?

Thanks for the help

Hi,
If you use a low-cost prebuilt relay board like one of these, you don't need a breadboard.

And if you use a sensor shield and pre-made cables, you don't need a protoboard either.  Take a look at:
Arduino Power stuff here: http://arduino-info.wikispaces.com/ArduinoPower
Arduino cabling here: http://arduino-info.wikispaces.com/Cables

And if you get one of these new Arduino-Compatible boards with 3-pin cable connectors built-in, all you need is a relay board (for up to 4 relays, more and you need a separate 5V supply).

IF your application only turns on 1 or 2 relays at a time in controlling the big device, you don't need an added power supply.
