ML8511 and OLED with ESP32 connection issues

Using Arduino Sensors
1

Hello everyone,

I'm having trouble with a project where I'm using an ML8511 UV sensor, an OLED display, and an ESP32. Unfortunately, I'm unable to connect to the web, and the sensor readings are not accurate. I've tried several troubleshooting steps, but I'm still stuck.

Could someone please help me review my code and offer suggestions?

Thank you
