Hello. I have a project that works with 4 moisture sensors turning on 4 motors. The problem I have is that using the code below, I do not know how to get the lcd to show the results from each sensor. It can be one then another after a 4 second delay or any other applicable design. Any help would be appreciated.
The first Sensor works perfectly displaying as wanted. Additional sensors is my problem.
const int sensor0 = 0; // Analog pin 0
const int sensor1 = 1; // Analog pin 1
const int sensor2 = 2; // Analog pin 2
const int sensor3 = 3; // Analog pin 3
const int MOISTURE_LEVEL = 600; // Analog pin 0 value after LED goes on
const int MOISTURE_LEVEL1 = 600; //Analog pin 1 value
const int MOISTURE_LEVEL2 = 600; //Analog pin 2 value
const int MOISTURE_LEVEL3 = 600; //Analog pin 3 value
#include <LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
void setup(){
lcd.begin(16,2); //Set LCD Display
Serial.begin(9600); // Set baud rate
}
void Relay(int normallyopen){ //
pinMode(13, OUTPUT);
digitalWrite(13, normallyopen); // Assign pin 13 to Relay 1
}
void Relay1(int normallyopen1){
pinMode(10, OUTPUT);
digitalWrite(10,normallyopen1);
}
void Relay2(int normallyopen2){
pinMode(9, OUTPUT);
digitalWrite(9,normallyopen2);
}
void Relay3(int normallyopen3){
pinMode(8, OUTPUT);
digitalWrite(8,normallyopen3);
}
void loop(){
int moisture = analogRead(sensor0); // Sets moisture to equal the value of the analog pin 0
int moisture1 = analogRead(sensor1);
int moisture2 = analogRead(sensor2);
int moisture3 = analogRead(sensor3);
Serial.println(moisture);
Serial.println(moisture1);
Serial.println(moisture2);
Serial.println(moisture3);
if(moisture > MOISTURE_LEVEL){
Relay(LOW);
} else {
Relay(HIGH);
}
delay(100);
if(moisture1 > MOISTURE_LEVEL1){
Relay1(LOW);
} else {
Relay1(HIGH);
}
delay(100);
if(moisture2 > MOISTURE_LEVEL2){
Relay2(LOW);
} else {
Relay2(HIGH);
}
delay(100);
if(moisture3 > MOISTURE_LEVEL3){
Relay3(LOW);
} else {
Relay3(HIGH);
}
delay(100);
// read the input on analog pin 0:
int sensorValue0 = analogRead(A0);
int sensorValue1 = analogRead(A1);
int sensorValue2 = analogRead(A2);
int sensorValue3 = analogRead(A3);
Serial.println(sensorValue0);
if(sensorValue0<400) {
lcd.print("Oversaturated ");
lcd.setCursor(0,1);
lcd.print("Zone 1");
delay(1800);
lcd.clear();
}
if((sensorValue0>400)&&(sensorValue0<600)) {
lcd.print("Ideal Moisture");
lcd.setCursor(0,1);
lcd.print("Zone 1");
delay(1800);
lcd.clear();
}
if((sensorValue0>600)&&(sensorValue0<1023)){
lcd.print("Dehydrated Soil");
lcd.setCursor(0,1);
lcd.print("Zone 1");
delay(1800);
lcd.clear();
}
