Every time I try to do something, I just need to search “Random nerd (whatever)” and there it is. I really appreciate the fact that you have spent so much time to document all these things for the Arduino and ESP32 worlds. I have learned so much from your articles and your ebooks are the greatest. All I can say is thanks for all that you have done for me and the community. God Bless You.

It seems LEVEL SHIFTER (board) doesn’t work for analog signals.

“string FROM one the other” (cant edit the post)

Hi! a simple code example, from esp32 to arduino mega, and from mega to esp32, please? just string form one to the other, bme sensor is too expensive , thanks a lot! If it wasnt for your examples, i would never have build a simple web werser page and home automation! greetings from argentina!

You might need an op amp for that.

I need to use a potentiometer that works well with an ESP32 and when I connect them up the readings are jittery but with an Arduino Uno they are rock solid. Will the level divider work for me?

Voltage divider is not efficient as it has a huge tolerance gap. I am using ESP32 and ACS712 sensor for current measurement with a voltage divider and it is not considerable accurate. Is there any other ways to convert it. The main constraint is that i am using it in a PCB which will be fitted behind the switch board. So, do you guys have any suggestions. Thank you in advance.

Hi Laurence.
Are you reading analog sensors and using wi-fi at the same time?
If so, you can’t use ADC2 pins. You need to choose ADC 1 pins. Learn more here: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/
I hope this helps.
Regards,
Sara

It gave me only 4095 readings. I knew that the sensor is ok because id already try it in arduino uno.. We all know that esp32 only accepts 3 v as input. Whats the problem with the level shifter or how can i fix it?
