That's an astable configuration, so, you change the value of the resistor and the time base changes, generating an audible frequency :) but it needs an audio amplifier D:

Oh... that is unfortunate. I did not rewrite it either. Does google still have the history of pages function? I am lazy to research it now... but you can try :)

in your comment says nobody would use that for morse code gen.

But my entire morse code rig "aside from the transmit port" is based off 555 IC

[CzDavid42]

Then I have probably miscalculated...
