The iTead Music Player Shield is based on CECL08D. The CECL08D chip can be used to decode MP3/WAV format audio file. The music player shield has SD card socket and USB interface, supporting USB and SD card play. Just plug and play!
This Passive Piezoelectric Type Buzzer is made of plastic, very eye catching colors. It can generate sound over 110DBA(!), so do not make it close to your ears when you test the buzzer. Includes build-in signal generator, just power on 6-12V and it will scream out loud.
Caution: may cause damage to human ears, security use only.
The Wolfson Audio Card, produced in collaboration with Wolfson, the premier mixed-signal semiconductor and audio solutions company, offers Raspberry Pi® users similar flexibility to a PC soundcard to capture audio alongside their camera, and experiment with stereo digital capture and playback.
Grove-Serial MP3 Player is a kind of simple MP3 player device whose design is based on a high-quality MP3 audio chip---WT5001. It can support 8KHZ~44.1KHZ sampling frequency MP3 and WAV file formats. This product has several peripheral ports: a standard UART Grove interface, a dual track headphone jack, an external interface and also a Mini SD card...
Grove - Recorder is based on ISD1820P, which can record 8~20 sec by set resistor and cycle play. It can offers true single-chip voice recording, no-volatile storage. Grove - Recorder is 100K and the total 10s for Recorder. This module is very easy to control, which can direct control by push button on board or by microcontroller.
The Grove - Speaker is a module consist of power amplification and voice outputs. The loudness can be adjusted by the on-board potentiometer. With different input frequency, the loud-speaker generated different tones. Coding the music into arduino, DIY your own music box!
Electronic brick of microphone can be connected to the analog I / O port, when speaking to the microphone, the analog value will be changed. A recorder can be made by reading and saving the analog value.
Active Buzzer is an integrated structure electronic transducers, DC voltage supply, widely used in computers, printers, copiers,
alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products for sound device.
8 cm (3.3") HiFi fullrange driver. Linear frequency response between 200 and 20000 Hz. Suitable for sur-round effect speakers, mini sub/sat systems. Due to the small size very suitable for model construction and as control speaker for electronic devices.
5 cm (2") 3W 8 Ohm miniature speaker with a plastic basket and plastic diaphragm. Broad frequency response and good voice reproduction. Particularly well suited to outdoor applications and where ambient conditions are generally unfavourable (e.g. high humidity).
This is a simple yet enjoyable twig to use. The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an analog pulse-width modulation output to generate various tones and effects.
