simple audio ADC

I would like to build a single line audio ADC on a teensy 3.5. that will convert to line audio signal to a VU reading.

Line Audio =~ 1.7v AC

In the uploaded images, the sin looking wave would be the original, and the other would be the result at full amplification. A simple electrical circuit should be ale to achieve this.


- Teensy 3.5 using the arduino IDE

- Adjustable peaks with 100k linear potentiometer

- a cheap opamp, maybe an OPA344

- 1/4 inch TRS audio jack for input signal

I would like the teensy 3.5 to be able to read the analog signal and to power the circuit. This will more than likely need to convert the 3.3v DC output of the teensy to 5v DC.

Must be able to communicate in written english.

Beceriler: Elektronik, Elektrik Mühendisliği, Arduino, Mikrodenetleyici, C Programlama
