Weather Clothes Recommender - Dress Appropriately

This is a mini local weather station that can be setup either on your backyard or even on your bedside window. It uses information gathered about the weather using sensors and an Arduino to make an appropriate recommendation given the weather outside.

Step 1: BoM

Arduino
LCD Display
Temperature sensor - TMP36
Breadboard
Jumper cables
Breadboard cables

Step 2: Wiring

Follow the table below for a concise guide for wiring the peripherals with the Arduino Board.

I/O	I/O Pin#	Arduino Pin#
Temperature Sensor	1	GND
2	A0
3	3.3V

LCD Pin#	Potentiometer Pin#	Arduino Pin#
1, 5, and 16	1	GND
2 and 15	3	3.3V
3	2
4	12
6	11
11	5
12	4
13	3
14	2

Step 3: Code

// built in arduino library

#include <LiquidCrystal.h>

LiquidCrystal lcd(12,11,5,4,3,2);

int tempVal;  //raw reading variable
float volts;
float tempC;
float tempF;

void setup()
{
  lcd.begin(16, 2);
  // clear old screen data
  lcd.clear();
  // text to be dispalyed on the screen
  Serial.begin (9600);
}

void loop()
{
 //read the temp sensor and store it in tempVal
 tempVal = analogRead(A0);
 
 //converting that reading to voltage by multiplying the reading by 3.3V 
 volts = tempVal * 3.3;
 volts /= 1023.0;

 //calculate temperature celsius from voltage
 tempC = (volts - 0.5) * 100 ;
  // Convert from celcius to fahrenheit
 tempF = (tempC * 9.0 / 5.0) + 32.0;
 Serial.println(tempC);
 
 // (column 0) of the second line (line 1):
 lcd.setCursor(0,0);
 lcd.write ("Temp: ");
 lcd.setCursor (7, 0);
 lcd.print (tempC, 2);

 lcd.setCursor (13, 0);
 lcd.write ("C");

 if (tempC <0){
 lcd.setCursor (0, 1);
 lcd.write ("wear winter coat")
 }else if (temp <20){
  lcd.write ("wear light coat");} else if (tempC<25){
    lcd.write ("windbreaker");} else if (tempC>30){
      lcd.write ("beach weather!!!")}

 // for farenheit temperatures
 /*
 lcd.setCursor(0,1);
 lcd.write ("Temp: ");
 lcd.write (tempF);

 lcd.setCursor (10, 1)
 lcd.write ("F");
 */
 
  delay(1000);
}

Step 4: Mount

Snake the wires through to the outside of your window under the screen. It's easiest to remove the screen, mount the temperature sensor and then replace the screen.
