For the last 12 hours, I've been trying to communicate with an I2C device with no success. The noise gathered by the ADC of the pins with a LRD was unrealistic. For this reason, I ordered a few different I2C sensors to solve the noise problem. I then tried to make a simple ...

I need help figuring out the default I2C pins for the ESP32-S3 DevKitC 1 model. I have esp32_hal_i2c.h and LiquidCrystal_I2C.h included in my code and other than that nothing that should change the device pinouts. I am trying to find the SDA and SCL pinouts. Please and thank you...
