research #2: 4ch volume control
using a digital potentiometer we can control the input volume for etch channel, to create a car speakers 4ch balancer and controller, all will be as a serial controlled module.
the pcb is allmost ready, files and schematics soon…
thanks to evgeny (aka: bradpilot) – for the pcb design & schematics from my ugly pen schematics..
will be eatching soon…
based on arduino atmega ( atmega168/328) – with arduino bootloader – this board control 4 digital potentiometers (x9c104p) – with 4 pairs of input headers on one side an 4 pairs of headers for the output.. serial connumication to control the volume level digitaly.
picture of the pcb – work in progress:
