I need a miniature transmitter + receiver + speaker. I would like to keep this all as miniaturized as possible and run on batteries as long as possible.
The idea is that when the transmitter button is pushed the receiver is initiated to cause some sound such as a chirp or some programmed sound to play on the miniaturized speaker.
Any ideas?
