The X9C503 that I have in my hands works at 5V, if it is connected to an Arduino Mega it works correctly, but to be able to use it in ESP32 you have to use transistors. The problem is that I don't have much experience and I didn't know that with transistors I had to use the 4k7 resistors to ground s...

I can't get X9C503 to work with ESP32 but it can with Arduino Mega. What do I need --> To be able to operate the X9C503 to lower the volume of an audio line input. I don't want to use common manual potentiometers. X9C503 Scheme: INC__| o o | VCC U/D__| o o | CS RH___| o o | RL GND__| o o | Rwiper In...

I'm trying to read the output of MSEGQ7 (DfRobot) from an ESP32. I have done 2 tests: Arduino Mega (works): - Analog input 0-5v - 10 bits (0-1023) ESP32 (not working): - Analog input 0-3.3v - 12 bits (0-4095) Comparative video on YouTube https://youtu.be/1cE5tiCEpbg As explained here https://github....
