Could someone help me finalize this project of mine?
I have found several beep circuits using the 555 but none to do what I need.
Attached is a schematic I found earlier, placed by Bernard and/or Sgt Wookie if I am not mistaken.
It works great, I played with the resistors turning R1 to 10K and R2 to 47k and it turns into a nice constant short beep alert tone...in case anyone is interested to build it.
I built it without the 2N2222A, just the right side of the schematic feeding it 5V.
Can I change this circuit somehow to do the following?
- Pressing a momentary push-button I get only a short beep that terminates after a fraction of a second EVEN if I keep the push-button pushed.
- Then, when you let go of the button and push it again its ready to do another short beep.....as quickly as I can press the button.
- Assuming the push button is NOT the also the power-on button; the 555 will be already on via a 5V supply.
....through a charge and discharge of a lytic cap maybe?
Thanks
