Cheap & quick PCB, 3D Printing, CNC machining and fabrication services from PCBWay: Hello bro, in this video I want to make an audio processor with Arduino-based. For the audio processor, I used the TDA7419 chip which was controlled by ARDUINO PRO MINI 5V/16MHz with the Arduino program/sketch that I got from rcl-radio at this link; PLEASE NOTE, the sketch that I used and included the link below has changed to make it works well with this circuit board. The display menu uses an SSD1306, 128x64 OLED display so that it has a simple appearance and does not take up space. Lot of feature/menu such as : VOLUME, BASS, MIDLE, TREBLE, INPUT SELECTOR, INPUT GAIN, LOUDNESS ATT, CHANNEL GAIN, TREBLE CENTRE FREQ, MIDDLE CENTRE FREQ, BASS CENTRE FREQ, and SUBWOOFER CENTRE FREQUENCY. This circuit requires a single supply 9V or 12V source.
