AX2358 Homemade 5.1 Remote Kit with 16x2 LCD

AX2358 is I used for this 5.1 remote kit project. It is Built-in 2-channel to 6-channel converter and 6-channel volume controller. It has 4 stereo inputs and one 6 channel input. Any stereo input terminals of AX2358 are selected, it will be directly converted to 6 channels and then output through volume adjustment but when the signal from the 6-channel input terminal is selected, it directly enters the volume adjustment and then outputs it without any processing. It has 6-channel individual volume control in this IC (0 to -79dB, 1dB/step).

This IC working by I2C communication. The data are transmitted to the AX2358 via the SDA and SCL. So I need a microcontroller. I choose the microcontroller is Atmega328 for this. This microcontroller programmed with Arduino UNO.
