Automatic irrigation system using Arduino Uno
* Code * #include<LiquidCrystal.h> LiquidCrystal lcd(12,11,5,4,3,2); #define moisturepin A0 #define signalpin 6 int moisturevalue = 0; void setup() { pinMode(moisturepin,INPUT); pinMode(signalpin,OUTPUT); lcd.begin(16,2); } void loop() { moisturevalue = analogRead(moisturepin); if(moisturevalue <= 400) { digitalWrite(signalpin,HIGH); lcd.setCursor(0,1); lcd.print("Motor is On "); } else { digitalWrite(signalpin,LOW); lcd.setCursor(0,1); lcd.print("Motor is Off "); } lcd.setCursor(0,0); lcd.print("Moisture Value...."); lcd.setCursor(13,1); lcd.print(moisturevalue); }
