My question is pretty straight forward (I guess) How can I connect/control stuff with such a high voltage. I've been trough all experiments (starters kit) and want to controll our home window shutters. They are electronical. The only thing is I don't know how to connect the wires of moving the shutters up and down. Because there's such a high voltage on them. I have a programming background; the code is not a problem AT ALL, only the schematics. Thanks in advance.

Hi Lewt,

This can be done by using a relay for example. It converts a logic signal to an electronic switch.
See, for example, the Relay Shield. I could give you a live sample if you like, I see you're Dutch as well

Good luck!

How are they controlled now? Remote control device, wall switch, etc? If they are remote, you might be able to hack a spare remote as a transmitter - this should be easy as you are dealing with low volts. If they are hard wired, I assume there is some kind of controller box (what stops the motor when the shutters are up/down)?

I've worked with these types of issues many times for both Halloween Props as well as Home automation. I always go with Solid State Relays. They are a little more expensive than a standard mechanical relay, but switch much faster. Depends on your needs. One company that I know of is EFX-TEK that makes a board called an RC4 that can house up to 4 SSRs and is controllable from a micro controller. I've always used Basic Stamps with that board, but there is no reason you can't use the Netduino the same way. PS... I'm Dutch too

I realy have nothing to add to this thread other than to say that I am NOT Dutch Pete.

Thanks a lot everybody! I'll look for a nice relay in the local hardware store.
