Hello, This thread is old, but I'd like to bring up some questions on how some of the components in this circuit works.
This is new to me, and I'd like very much to know it thoroughly. The basic Monostable multivibrator with a 555 is attached as a picture. (I googled it.)
A couple of questions:
1) This circuit I've attached will consume power if left connect like this. Yes?
2) In the 555 circuit you, crutshchow, attached, there is V+ and V2. What is V2? If I want to use just one power source that's V+, can I just replace V2 with V+?
From what I've learned so far, the trigger Pin 2 needs a negative pulse to start charging of the timing capacitor. I see that you've fed the Output into a NPN and PNP combination. (Q1 and Q2)
Can you please explain why you've done this and how Q1 and Q2 are functioning in this circuit?
Thank you
