Code for the microcontroller to communicate with the database and to manage the sensors for the smartpot project.\
run '. $HOME/esp/esp-idf/export.sh' in the directory you want to build. This will make the tools available in the directory you want to work with.
Then find the port esp32 is attached to with 'ls /dev/cu.*' (for macos).
then 'idf.py -p THE_PORT_NAME -b BAUD_RATE flash' command will build and flash the code to the esp32.
'screen /dev/cu.PORT_NAME BAUD_RATE' command will open the output window of the esp32.
BAUD_RATE = 115200.
moisture sensor:
completely immersed in water --> 1.2V output.
Air -> 2.5V output.
