ESP32 ADC - Read Analog Values with Arduino IDE 

You can find the complete project details (schematics + source code) on my blog ►

Thanks so much, concise and clear

Thanks Man. Life would have been so difficult without you !!

Great explanation. Using an interrupt instead of delay(1000) would be nice for integration with other functionality. Have you done a video on interrupts with the esp32? Thanks for sharing your expertise.

شكرا جزيلا !

Rui Great Work this really help me out. :)

I miss the ADC calibration part.

So with both power and ground connected, is it doing pull-up and pull-down on this simultaneously, or is that only for digital switches?

now for a scaled 0 to 10 vdc input signal with zero and span adjustments then oled display output value with tenths resolution 00.0... thanks a lot...:)

hiii .....i can't found port option in Arduino ide.......since it is grey colored.....what have to do to enable the port option for selecting the corresponding port.

Can I use 5v pin

esp32 & st7781 tft lcd display pin connection help

Hello sir , I am also using potentiometer but adc value fluctuate a lot also noise glitches visible .. plz guide me what I can use it will be really helpful thankyou

How much ohm should the potentiometer can have?

Thanks

Great tutorial. Can help me with some project? I use ESP32 Devkit V1 and i connected digital led WS2812B, 4 channels relay module , DS18B20 sensor, and capacitive soil moisture sensor.I supplied all of them with Vin. The capacitive soil moisture sensor shows different value when i turn on digtal led or relay module, what's maybe i wrong with connection or i need to write code for adc. Capacitive soil moisture sensor connect on GPIO34 , digital led is in GPIO23, DS18B20 sensor in GPIO4 and for relay module i use GPIO 2, 26, 27, 33.

Thank you for the fast tutorial, please help me in getting the real linear value on any of ESP32 ADC channels ,

Boas! Muita bom Rui! Olha... onde é que compras os teus ESP32 ?

How many analog inputs can ESP32 handle?
