Wouldn’t the capacitor do just that, if I then somehow reversed the negative portion of the wave and then smoothed it some? Unfortunately, this circuit will not generate a DC voltage, if the output is taken on the right side of C2. The higher-power 2N is a very similar NPN transistor that can safely switch three times as much current as the 2N The 2N is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.

After getting results, just make an if-else condition in the software depending on tramsistor ADC value that you read.

If it was fully OFF, it would be not conducting at all. Also, wouldn’t the peak detector vary between If you do not, try lighting an LED if the analog read is higher than, for example, The transistor will amplify these small changes so they can be viewed easily: You can do this with minor changes to the schematic you have.

However, I am not sure of this. And doing this is easy with a simple, single capacitor.

Felice Pollano 5 It is designed for low current and powermedium voltageand can operate at moderately high speeds. A microphone generates an AC voltage, which is sometimes negative and sometimes positive and it changes most of the time.

Also, notice that there is no more an output capacitor. Here’s what I want instead:.

This means that you will have an output voltage somewhere between 0 and 5 V, depending on the sound level. Thank you for your interest in this question. A capacitor does not let the DC to pass, but lets AC pass easily. How do I make it vary the full 0V to 5V, 0V being ‘quiet’ and 5V trannsistor ‘loud’, with everything in between linear?

If you take a car siren and put it near the electret microphone, it will be teansistor sine wave from with a peak to peak amplitude of 5Vpp with a frequency of about Hz.

Can you add a diagram of this? Maybe you should try to make the supply voltage 5V. I’m looking to simply read the generic sound level from an Electret Microphone.

However, trnsistor comment above ignores the DC offset.

The complementary PNP transistor is 2N Perhaps I’d need a diode to not be passing negative voltage to the Analog comparator? Would you like to answer tgansistor of these unanswered questions instead? But before that, you should understand the circuit.

Yes, but a diode will drop 0. From Wikipedia, the free encyclopedia. Ehryk Nope, the output will be somewhere between 0 and 5V.

Note that you could add a second inversion in this instance by simply interchanging R1 and the microphone. The Arduino has 6 analog inputs, which read for 0V-5V. An AC signal will be centred on the DC bias point.

You can beg Google for more detailed information. Imagine that there is nothing else but the below rransistor However, it will be a sine wave added with a DC value.
