You can do this with minor changes to the schematic you trnsistor. Imagine that there is nothing else but the below schematic:. Think of a sine wave. Would you like to answer one of these unanswered questions instead?

I understand most of that, thank you. But remember, we had some biasing to it which is a DC voltage. Simply invert the output a second time, using a 2 stage amplifier. When there is a whisper, the peak transostor peak amplitude will be about 1Vpp with changing frequency because of the speech.

Then, read the analog value on the collector of Q1. Perhaps I’d need a diode to not be passing negative voltage to the Analog comparator?

With the right component values, you will be able to have an analog voltage level depending on the sound amplitude.

Further, is there some reason why this is so uncommon, or undesirable?

I realize I could easily correct for this in software, but it just seems backward to me in a way and 2nn3094 cannot find any examples of a non-inverting output with a PNP transistor. If this is the case you need to state it clearly. What you’ll have at the output is AC, a capacitor blocks DC. Ehryk 4 11 Transjstor order to solve your final question anyway, you have to rectify even with a single diode the output and apply the result to a load a resistor would be fine and feed this to the arduino analog input.

If this is not the case, n23094 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.

Views Read Edit View history. Thank you for your interest in this question. The transistor will amplify these small changes so they can be viewed easily: If you have an oscilloscope, view the waveform on the output.

That means it will go to 1V and come back to 0V.

This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. Here’s what I want instead:. Ehryk Yes, you can add an output capacitor and an envelope detector. It looks like I want the above with an envelope detector, however that would only get me from 0V to 2.

The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N However inverting or not will NOT solve the stated problem – generating a logic 1 or 0 depending on the loudness.
