An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
[bctt tweet=”A transceiver unit to broadcast audio MP3 files over Wi-Fi” username=”OpenElectronics”] In this article, we want to propose you what can be considered as the natural evolution of project Ethernet Broadcaster; the goal is still the same, i.e. allowing broadcasting of music or customizable audio messages. Besides adapting to the ever-growing trend of…
“The problem with high tech music players is they don’t have any flash! They non conspicuously just produce music from a drab dull lifeless box. In the times of early music the mechanisms to reproduce sound were fantastic. They gave you something to watch and admire while you listened to your favorite music. My goal was…

It is based on the DFRobot module, and enables the playing of musical tracks that have been recorded on a microSD or on a USB Pen Drive; it is supplied with outputs that enable to connect it to the AUX socket, the one most Car Audio Systems are provided with. Car Hi-Fi systems –…
Let’s test out the capabilities of the DFR0299 audio player module, an ideal choice for Arduino but also for many stand-alone applications. In this article, we decided to design and propose a demoboard for the DFR0299 module we already used in the ‘Presepino’ project; this module will function as a development platform for…
A compact stereo amplifier that may be used at home as well as in the car, and also to substitute broken audio power amplifiers or to create bench power amps for the analysis of audio devices. When repairing audio devices, it is always useful to have a BF amplifier on your workbench; all the…
In this second and final post we will go deep inside the Ethernet audio streaming transceiver firmware. Recently, we have presented an Ethernet audio streaming unit. In particular, we have shown how to configure the boards to work with other similar devices or with VLC Media Player, setting up a point-to-point or a broadcast…
In the previous posts we presented the project of an an embedded MP3, capable of playing and recording audio sequences by means of appropriate commands. The interaction modes, as well as the communication interfaces cover a wide range of possibilities, for example it is possible to easily use UART, USB, I²C or bit banging on…
The operation principle of this circuit is very simple and easy to describe. The basic idea consists in supplying a device that is capable of operating since it is first started: this is why we created a software, in order to automatically generate a preset configuration file, with default values, that can be modified at…
It is always convenient to dispose of an easily adaptable module that can play musical tracks: it allows to easily implement vocal syntheses to insert within a promobox, or to place items in the shop windows or in well trafficked areas, or close to automatic doors or to turnstiles, or to other…
. The objective of this project is to build an Arduino voice shield to empower thousands of voice related applications! All this mostly thanks to an integrated ISD1790PY chip. This particular voice/TTS feature can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home…
