Homemade Arduino Chicken Incubator

The Code I Used:

//Code by NonchalantWombat //Composite of various other code available online, using DHT.h, Wire.h, and LiquidCrystal.h libraries

include "DHT.h"

define DHTPIN 2 // what digital pin we're connected to

int ledPin1 = 3;

define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321

DHT dht(DHTPIN, DHTTYPE);

include <Wire.h>

include <LiquidCrystal_I2C.h>

int Lightpin = 3; int TempPin = 2;

LiquidCrystal_I2C lcd(0x3f,16,2); // run ic2_scanner sketch and get the IC2 address, which is 0x3f in my case,it could be 0x3f in many cases

void setup() { lcd.init(); // initialize the lcd pinMode(Lightpin, OUTPUT); // set pin to output pinMode(TempPin, INPUT); // set pin to output Serial.begin(9600); Serial.println("DHTxx test!"); dht.begin(); }

void loop() { delay(8000); float h = dht.readHumidity(); // Read temperature as Celsius (the default) float t = dht.readTemperature(); // Read temperature as Fahrenheit (isFahrenheit = true) float f = dht.readTemperature(true);

// Check if any reads failed and exit early (to try again). if (isnan(h) || isnan(t) || isnan(f)) { Serial.println("Failed to read from DHT sensor!"); return; }

// Compute heat index in Fahrenheit (the default) float hif = dht.computeHeatIndex(f, h); // Compute heat index in Celsius (isFahreheit = false) float hic = dht.computeHeatIndex(t, h, false);

// Serial.print("Humidity: "); // Serial.print(h); // Serial.print(" %\t"); // Serial.print("Temperature: "); // Serial.print(t); // Serial.print(" *C "); // Serial.print(f); // Serial.print(" *F\t"); // Serial.print("Heat index: "); // Serial.print(hic); // Serial.print(" *C "); // Serial.print(hif); // Serial.println(" *F");

if (f > 101) digitalWrite(Lightpin, LOW); //This turns the light off if (f < 99) digitalWrite(Lightpin, HIGH); //This turns the light on

String TempString = String(f); String HumString = String(h);

//if (f = nan) //{ // // action A //} //else //{ // // action B //} // Print a message to the LCD. lcd.setCursor(0,0); // lcd.backlight(); lcd.print("Temp:"); lcd.setCursor(5,0); lcd.print(TempString); lcd.setCursor(0,1); lcd.print("Humid:"); lcd.setCursor(6,1); lcd.print(HumString); delay(2000); // lcd.setBacklight(0);
