Hello,
I'm trying to make a device that can convert a Morse code audio file to a
flashing light. I have the Morse message recorded as a music CD consisting
of 800Hz tone for the dots & dashes & silence for the spaces. I want to be
able to convert the audio output from the CD player to an on/off signal that
I can use to flash a light. (the idea being that I can 'flash' a message by
pressing play - this is to be used to repeatedly transmit the same message
to a several groups of Scouts on a hike).
I have tried using an LM2719 frequency to voltage converter to discriminate
between tone & silence but without success.
Any ideas gratefully received.
Gavin.
