Hey guys! I have the following ESP32 and I have to connect multiple sensors to it. So far, all my sensors required digital pins , and I’ve used pins like GPIO 32 33 25 etc, both as input and outputs.
I have a sensor for soil moisture that requires analog input, so I can read his values and map it so I have a percentage display. I tried different pins and none works , and I got really confused which ones I can actually use for analog input data.
The reading I get is 4095 , probably because all pins output 3.3V and converted to digital is 4095.
So, which pins can I use to read analog values ?
