Arduino Powered Penta Display

Another Update, the 10v Feed provides enough current when the speaker is actually playing, very bizzare, but also a relief. Now i need to get my coding hat on and get this Audio Spectrum going.

Sounds like a ground issue. A stock 7805 should happily supply 1.5A which should be more than enough for the ESP32 and the OLED. Can you do a quick drawing of your wiring?.
