How to make an extremely simple but visually effective VU meter at 0.9 inches OLED displays SSD 1306.

This time I will show you how to make analog-style stereo VU meters on small 0.96 inch OLED displays. Some time ago I received small yellow OLED displays that are ideal for this purpose.

The device is made according to the instructions of “stevenart” in the forum where you can also find the original code(for SH1106 Oled). Specifically in this case the codes are slightly modified(SSD1306 Oled), and in the hardware, part is added a simple input circuit (envelope follower) so that the VU meter can be connected directly to the output of the audio amplifier. The device is very simple to build and contains only a few components.”
