Use of stereo has become common in our lives. They are used in cars, TVs, music players etc. And it is essential at least to control their volumes. Suppose there is a stereo amplifier which functions pretty well but it does not have a remote. It would be very annoying if its volume cannot be controlled. So this project is useful as it creates a device which makes use of any existing remote to control the volume. For controlling the volume, we use a volume controller IC. The electronic volume controller IC PT2258 is a digital potentiometer which can be controlled using I2C protocols. It is used to control the attenuation for every combination possible from 0 to -79 dB/step. Universal IR receiver is used to decode the IR codes and the data will be transferred to the Arduino which in turn communicates with the IC PT2258 and controls the volume. The device also consists of two buttons, which are used to synchronize the IR code of the existing remote with the device. So the user will be able to use the device easily.
