Arduino 32 band audio spectrum visualizer / analyzer This project is for making a 32 band audio (music) frequency spectrum analyzer / visualizer using Arduino. Expected audience of this project is any ...

All it took was an audio jack and two jumper wires to get the Arduino ready to receive the audio file. His firmware reads the Binary Frequency-Shift Keying encoded data as the audio is played ...

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 ...

In this project we will use a normal Electret Condenser microphone with Arduino and try measuring the sound or pollution level in dB as close as possible to the actual value.

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

The farmers and vendors in the Philippines classify coconuts through knocking manually either by bare hands or knife as 'mala-uhog', 'mala-kanin' and 'mala-tenga'. The said technique is well-known but ...
