I am trying to make smart irrigation system using dht11 sensor and water level sensor with bolt iot and arduino.I am getting errors in arduino code and python code .Could anyone help me??
This is my python code .Plzz check and tell me whether it is correct or not.I have also attached screenshot of errors .
