This project is for making a 32 band audio (music) frequency spectrum analyzer / visualizer using Arduino. Expected audience of this project is any audio enthusiast , student or a beginner who has ...

Yeah, if you are going to use a real Arduino and an LCD shield that is pretty expensive for a frequency counter. I’m not entirely sure what your requirements of reading 3 frequencies are.

This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in digital signal processing (DSP) and electronics labs. The author ...

This proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He&#8217… ...

Circuit Diagram: Circuit for this Arduino Sound Level Meter is a very simple in which we have used the LM386 Audio amplifier circuit to amplify the signals from a condenser microphone and supply it to ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the ...

The range of the frequency to be measured by a measurement device depends on the purpose of performing the measurement. The frequency measurement device is built specifically according to its range ...
