A peak detector allows it to measure signal amplitude and there is a phase detector. By connecting the output of the Tsunami to an analogue filter or an audio amplifier, and using the Tsunami’s input ...

Turn an Arduino Uno R4 into a powerful sound synthesizer and MIDI sequencer! Explore audio synthesis with this Basic Synth project.

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 ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors ...

Meet the Production-Ready Arduino Compatible HQ record and Playback Audio Module! With ease, you can record and playback up to eight sound bytes using your own voice, or PC. There is an on-board ...

This prototype consists of PIR sensors as a detector to detect movement from birds and using LC oscillator type colpitts with Piezo Ultrasonic sensor as repeller. The results of the experiment are the ...
