I am going to be permanently incorporating a locating device into another product.
similar to a [“key finder”, this device should have audible and visual confirmation when activated.
So basically, I would like a little walk-through on how to assemble one.
I plan on using a small Piezo buzzer, a bank of 3 L.E.D. and probably a 555 timer.
The products you offer in which I have been interested in are as follows.
Optimally, I would like the smallest possible unit for my solution.
This is why I have listed the transceiver which is exponentially smaller than the receiver, and also seemingly more durable (the product is going to be flexible and the smaller unit wont break when the product is flexed). although I will not need to transmit anything from the device itself, but only to the device. Price is also a determining factor. I am also open to other product recommendations.
Ideally, the finished unit should, upon activation, make the buzzer and L.E.D. bank turn on and off twice quickly, which is probably where the timer will come into play.
If someone can show me a schematic or blueprint that a layman can understand or some other form of tutorial or guide that would be fantastic! Or possibly create a simple one for me?
Thanks!
