[Coco] A little off topic

[William Mikrut]

Ok, so keep in mind this is for a 5th grade project... and will get my
daughter into working with components... that's the main point of the
project!

She came up with an idea --- to try and keep the dog and cat away from each
other, build a device that beeps when they're close.
So, I went to work thinking up how to do this and tried to keep it as
simple as possible.

I was going to start with an RF Transmitter & Receiver for use with Arduino
DIY Projects:
( I am not embedding links here because I am not advertising anyone site )

I figure without an external antenna -- maybe the transmitter/receiver can
be a couple feet away and function... any further and the link is broken.
I planned to attach a 555 timer pulse to the transmitter data pin and keep
sending a pulse all the time.

On the receiver have a transistor (or such)  hooked up to the data pin.
When data is received, it receives the 555 pulse, and in the transistor
circuit have a small piezoelectric speaker that sounds out the 555 pulse
from the transmitter.

Volia -- close proximity -- loud pulse from the small speaker.

Epic failure -- or plausible project we can build?
Thank you!
