SoundDuino is a Sound Recorder/Player whic is able to Play the sound files from the Micro-SD memory card or Record sounds to the memory with your desired file name.
Communication to the Shield is through UART and everything is taken care of in the Arduino Library that comes with it.
There are commands to play or record.
Sound quality is very high and it can play wave files Stereo 16 bit 48khz.
VGADuino is a shield that is made for Arduino with all the libraries and samples.
With VGADuino you can connect Arduino to any kind of TV or Monitor with VGA 15 Pin connector. The user will be able to show text, numbers, draw lines, tables, shapes and even small images on the screen. You can use the TV or Monitor as a big display for Arduino with this shield.
Wave III is a two channel Stereo Audio Recorder and Player module with FAT File System support. The module can record audio on Micro-SD card or play Pre-loaded files with high quality from the Micro-SD card. Recording and Playing is 2 channel Stereo with 10-bits resolution Wave III supports FAT File System so user can call file names to play or create a file/folder to record using AT-Commands. Communication is through standard UART serial port with Auto-Baud Rate detection system. Low Latency Commands makes it suitable for applications that multiple audio files need to be played consecutively. It can be connected to any micro controller or device that has standard serial RX/TX port like Arduino. Using the module is very easy and hassle free. It has a very good document describing the commands and features. Audio quality is super high and supports both 8 bit and 16 bit wave audio format. Foot print is available for Altium Designer.
This is a DIY Walkie Talkie Radio shield based on RF module RFM12 designed for Arduino Uno.
Audio packets are sent digitally and the Arduino code is pretty simple to modify.
There is a speaker and microphone with a PTT buttonon board.
System works like a real Walkie Talkie Radio.
Hold PTT, talk, release and listen.
This board is made based on the open source EspRadio project by Ed Smallenburg.
This board is a complete Internet radio based on ESP8266 Module and the Arduino. The board has a stereo earphone jack plus two speaker connectors and a on-board 2.5w HiFi amplifier.
The mp3 decoder is VLS1053B and the sound quality is amazing
all of the source codes , BOM , schematic and PCB and Arduino codes and libraries are included
