hi,
I used esp32 and ADC converter in the load cell, and esp32, vdd, and gnd were shorted. However, if the power is not turned on, a short circuit will not occur.
I don't know what the problem is and how to solve it. Please help me
Yes I understand, with what you have stated I do not have a clue either. Put together a schematic showing what you are describing. Explain how you know they were shorted. A short is a short whether the power is on or not, the difference is the potential damage.
Hi,
Are you measuring a short circuit here with power ON. and the DMM in RESISTANCE mode?
You cannot measure resistance with a DMM in a circuit that is powered up.
What VOLTAGE do you measure across those two points.
Can you please tell us your electronics, programming, arduino, hardware experience?
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Thanks.. Tom... 
I moved your topic to a more appropriate forum category @yunshy.
The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.
In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
Thanks in advance for your cooperation.
