Hello bro, in this video I want to make a stereo amplifier with an Arduino-based tone control.
For the audio processor, I used the TDA7439 chip which was controlled by ARDUINO PRO MINI 5V/16MHz with the Arduino program/sketch that I got from rcl-radio at this link; rcl-radio.ru/?p...
PLEASE NOTE, the sketch that I used and included the link below has changed a lot so that it works well with this amp circuit.
The display menu uses an SSD1306, 128x64 OLED display so that it has a simple appearance and does not take up space.
Some of the menus available are VOLUME, BASS, MIDLE, TREBLE, BALANCE, INPUT SELECTOR, INPUT GAIN, AND POWER ON/STANBY.
For the power amplifier I used the TA8221 which has been proven to produce good sound.
The overall circuit requires a single supply 12V voltage source.
