#190943 - Tweaking after simulation
Responding to: Ralph Sac's previous message
I simulated the original cct
https://photos.go...E1Xfz9Idqk and I didn't like the duty cycle of audio o/p waveform
so I modified it to 50% duty cycle for higher volume waveform and frequency that matches resonance of piezo buzzer


Hope this leads to perfection.

Unfortunately insert image does not work anymore in this site!
OOps! forgot to add piezo buzzer to the simulation to see its effect on o/p Waveform.
Working on it.
