I thank all who have commented, it all helps me. It helps in joining the Dots
You can probably see by my comments, I am mentally challenged when it comes to Electronics, and forums also for that matter.
I just tried another 1K resistor and it DID improve the sensitivity.
My objective with my Arduino Knock is to make an peizo digitizing sensor for my DIY cnc machine.
I have been experimenting with mechanical digitizing probes, but with the vast amount of make & break contacts, the points give out at about 30 - 40,000.
So I saw this fellows idea, but I cant contact him. I wish I could, I can probe and produce Gcode no problem, we could help each other.
So it's trial and error, and with the the help from others I hope to finally have some success.
