Hello,
I tried to do this project on my breadboard but it does'nt work (i'm a beginner).
I just replaced the 33k resistor by a 47k resistor because I didn't have one.
The output signal is on the 3rd pin of U2 right ?And I should hear 2 tones like a siren no ? ( right now i hear nothing)
Is there something wrong on this schematic or something badly indicated ?
thank you
