Raspberry Pi Bluetooth Speaker: Play Audio wirelessly using Raspberry Pi

In this post we will build Raspberry Pi based Bluetooth Speaker by fusing the power of A2DP, Linux and audio codec to stream the data packets from an audio source to an audio sink wirelessly. To do so we are going to hack a little bit of Linux system and write a piece of code in bash and python and we will be in business.

IR based Wireless Audio Transmitter and Receiver Circuit

Today in this Article, we will learn how to build a Crude Wireless Audio Transfer Circuit Using IR LEDs. Using this circuit you should be able to play songs from your IPod, mobile or computer to an external speaker without having to connect them directly though an AUX cable. The circuit comes with many limitations and there are better ways like Bluetooth to play songs wirelessly, hence this article only aims to help you understand simple audio circuits and at the same time have fun building it.

Simple Tone Control Circuit

In simple language, Tone Control Circuit is the circuit, using which we can control the output of audio device. To control the output means we can control the Volume, Treble and Bass of the Audio output. So, to achieve this aim we have to control the output frequency. If we can control output frequency than our aim is achieved!
