ok.
credit goes to Bruce and Wilf for coming up with this independantly but
seperately.
first connect your unused inverter outputs together.
This would be pins 3 and 7.
second, connect one of these pins to the + of your sound effect circuit,
LED, or watever
third, connect the inputs of these inverters together and then connect one
of them to ground (-) .
This would be pins 12 and 17.
fourth, connect the - of your sound effect circuit , LED or watever to
ground (-) .
thats it, werked for me.
you COULD just use one inverter (like pins 3 and 17) but if you double em
it means more power. In the case of a piezio buzzer this is translated
into more volume. (needed for "whining, whizzing" servos!)
