@Omar: you read some distance to variable distance. So this variable now contain some more/less random long number. Then you call digitalRead(distance) where you read pin with this number - so you read some random (maybe even non-existent) pin. With digitalRead you read digital, so result is else HIGH or LOW (which are 1 or 0). And then you compare valoue of 1 or 0 (obtained from random pin) with values like 8 or 20. Do you see, why it does not work this way?

| Feb 22, 2017 at 19:17 | comment | added | 6v6gt | Your collection of if statements has holes which could result in no output to the lcd. For example, if Grove_Water_Sensor is LOW and distance is 10 would result in no output. | |

You might want to change digitalRead(distance) >=20 to just distance >=20
