The integrated circuit 555 has no limits, this FM transmitter circuit,
the IC 555 is designed as an stable multivibrator as usual. But the
tension control pin is used to connect a piezoelectric element instead
of the capacitor disk. The piezoelectric element generates a voltage and
the output pin is connected to an antenna wire 30 inches for the
transmission of signals.Just tap the piezo element and you can hear the
sound on an FM radio station. The range is very short.
