Hello all. I am new to wireless and am doing a small experiment. The premise is fairly simple.
I have a mercury switch (2 actually but either will cause the circuit to close) rigged up to a pair of small lights in one enclosure. To a second enclosure, I have a buzzer and another light. when the circuit is complete, obviously, they go off. Now, what I want to do is somehow take that electrical signal being sent to the buzzer and second light and transmit it wirelessly to a separate receiver that will make the buzzer and light go off. basically, all I need is a on state, off state kind of thing. It sounds simple enough, but I have never done anything like this before and am lost as to what direction to take :oops:
Also, the receiver/light/buzzer will be in a single enclosure. It has to be able to reach 20-30 feet through a house, or a car. Basically, the signal has to be strong enough to travel through metal and wood n the like. Can anybody give me any starting points?
If you have more questions, ill do my best to answer. Thanks all.
If you’ve not done simpler project with microprocessors, then you should.
And instead of you coding for microprocessors, there’s a no-code solution approach to this.
which way do you want to go? (is this a learning thing or a get it working fast thing?)
No, I have never worked with microprocessors before. Overall, I want this to be a learning thing, but I want to take it in steps. If there is a no code way for this, Id rather start with that first. If possible, the cheapest easiest fastest way first, then make it a bit more and more complex as I get better and understand this stuff more and more. I hope I am explaining myself correctly lol.

First, read introductory material, look at other people's code for small simple project. Do you own very tiny project. Then a larger project.
Just as we learn other things in life.
If you have no experience in DIY electronics- maybe start there first, before microprocessors. See also “Make” magazine.
Lots of microprocessor tutorials, texts, on-line stuff.
The Arduino microprocessor boards world (cheap) and free development tools, plus uploading your programs via USB/serial is a popular learning path:

And example code (some good, some not!)

In the magazine Nuts 'n Volts, “Smiley” wrote a series of introductory articles in the last year or so, on Atmel AVRs.
Thank you very much for your reply stevech. I have been doing some reasearch and came across this website : http://www.electronics-diy.com/electron … php?id=726
it looks simple enough for me to grasp and it might do the trick for me. I will give it a shot and probably be back with questions lol thanks.
