This circuit is from afrotechmods on YOUTUBE. I have found afrotechmods very useful for my studies. I'm using it as a learning circuit so have a few questions to ask.....
I know the output "on time" can be varied by changing the values of C2 and R5. I'm trying to achieve an "on time" for the LED (D2) for 1 second but have noticed that this seems to vary in relation to how loud the clap is. The softer the clap, the shorter the "on time seems to be. Can somebody tell me how I can achieve a stable 1 second output or "on time" for the LED at D2?
I would also like to convert the circuit so I may use a normal 9V battery. What would I need to consider when it comes to the component values etc?
How do I determine the maximum amplification that can be achieved by manipulating R4 and R3?
Lastly, I have replaced R6 with a 100K potentiometer so I can raise or lower the threshold of the comparator. Is this the right approach?
Once again, thanks for your help. JDR04
