Hello Everyone!
It's my first post on the forum so take it a little easy on me eh?
I am trying to come up with a circuit using Radio Frequencies for 2 items to essentially ping each other. In essence, 2 keychains with an RF circuit (that i dont have) that activates a speaker on each one. I know how to wire the speaker, but is it possible to use the output of the RF on a transistor to act as a switch for the speaker to turn on?
Currently i am thinking of using http://rentron.com/Files/rf.pdf as the transmitter and receivers... but i really dont know a whole lot on how they work or even if they are the right part.
I do have some electrical knowledge... mostly in transistor logic, PLC and some digital logic for robotics, but idk how well it would translate onto this.
EDIT: Also was thinking, is it possible to modify the frequency Via dip switch? That way if i make multiples of the circuit, it doesnt ping them all at once and make someone deaf? =D
Thanks in advance for any advice!!
