Sinhala Arduino Tutorial 10|Soil Sensor Module

                 

1st code-

 

int soil = A1;   //connect soil to A0
int value= 0; //define value 0
void setup()
{
 pinMode(soil,INPUT);
 Serial.begin(9600); //this is not necessary-but to show value to pc

}
void loop()
{
 value = analogRead(soil );  //read value-analog from A0
 Serial.println(value);    
 delay(100);
}

2nd code-

int soil =A1;

int value=0;

int led=13;

void setup()
{
 pinMode(soil,INPUT);

 pinMode(led,OUTPUT);
 Serial.begin(9600); //this is not necessary-but to show value to pc

}
void loop()
{
 value = analogRead(soil );  //read value-analog from A0
 Serial.println(value);    
 delay(100);

 

if(val>340){

digitalWrite(led,HIGH);

} 

if(val>930){

digitalWrite(led,LOW);

}

delay(100);

}
