Hi guys,

I wonder if anyone can help me with this simple problem I have as art of my school project..

I am trying to turn an electrical current on and off down a wire via a wireless signal on a key fob.

The cable is connected to a light. All I need to do is switch it on and off -remotely. Yes, I have seen remote light dimmers, but all I need to do is switch the light on and off (not dim) and make the circuit as cheap and easy as possible.

Can anyone tell me what the simple circuit diagram should look like, and what components need to be on the pcb etc?

Plus if anyone can - what the circuit in the key fob should look like.

Yes, but he did say he was a newbie. You seem to have failed to direct him to any web sites that would straighten him out, or to straighten him out yourself.

Voodoochile:

Check Wikipedia, or do a web search, on "Multi-posting" vs. "cross-posting". The former is considered sufficiently bad form that the net nazies will trouble you over it, the latter may cause a raised eyebrow if you do it within reason, but is often effective and provides some nice cross-pollination between groups.

Not even wrong. A good rule: Click the link before responding to the post. (Someone else in another of the parallel threads also thinks I'm an idiot, while demonstrating that, in fact, it applies more to that poster and his inability to do simple things like click links.)
