2N3904 Datasheet, Equivalent, Cross Reference Search
The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. If this is not the case, can you please explain “I’m not looking for a logicthe Arduino’s analog inputs have a bit ADC that gives for 0V-5V, respectively” in this context.
This is because of the capacitors. Unfortunately, this circuit will not generate a DC voltage, if the output is taken on the right side of C2.
If this is the case you need to state it clearly. IF you are talking about DC levels the question is still unclear. You can do this with minor changes to the schematic you have. Here’s what I want instead: A capacitor does not let the DC to pass, but lets AC pass easily. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. You will probably need electrolytic capacitors.

You can use values up to uF. The transistor will amplify these small changes so they can be viewed easily:. AC is what I’d be looking for there, right? Would you like to answer one of these unanswered questions instead?
The same value resistors and capacitors, the same 2n transistor, added to the output of your existing schematic, would provide a second inversion. Simply invert the output a second time, using a 2 stage amplifier.
I’m looking to simply read the generic sound level from an Electret Microphone.
With the right component values, you will be able to have an analog voltage level depending on the sound amplitude. Felice Pollano 5 This is what amplification called.
Then, read the analog value on the collector of Q1. Is there a reason for this beyond being uncommon? Retrieved from ” https: If it was fully OFF, it would be not conducting at all.
This page was last edited on 18 Octoberat Can you give circuit diagram for this? How do I make it vary the full 0V to 5V, 0V being ‘quiet’ and 23n094 being ‘loud’, with everything in between tranzistor Commons category link is on Wikidata.
What you’ll have at the output is AC, a capacitor blocks DC. I realize Tranistor could easily correct for this in software, but it just seems backward to me in a way and I cannot find any examples of a non-inverting output with a PNP transistor.
We have blocked the DC portion of the voltage on the electret microphone. R1 is transistlr supplying power that is needed by the microphone and this is called biasing the microphone. What if we combine the two circuits mentioned above. Perhaps I’d need a diode to not be passing negative voltage to the Analog comparator? Reading your question and comments it appears that your questiojn is not clearly stating what you want.
