# Objective
Nigeria is a very hot place. Temperature averages 30 degree Celsius and even at Night the temperature is hot. The aim of this project is to regulate temperature by turning on the fan whenever the temperature reaches a certain level and turn it off whenever the temperature drops.  This helps to conserve energy and also to improve comfort for the owner.

# Steps
## The first step is connecting the motion sensor to the breadboard. The motion sensor has three pins. It is labelled pin is for 5v , the second is for output, and the third is for ground. You place the motion sensor on the board and use a jumper wire to connect the 5 volts terminal of the motion sensor to the 5 volt pin on Arduino.  You then connect the output to pin of the motion sensor to pin 2 of the analog headers of the arduino. Finally connect the Ground pin on the motion sensor to the Ground pin on the arduino.

notes: This project requires only  few parts, and because you're using a breadboard and pre-cut jumper wires, you won't need any tools at all except your computer and USB cable to connect the Arduino.

## Plug the LED's anode (the longer leg) into digital pin 13 on the Arduino. Plug the LED's cathode (the shorter leg, and/or the leg on the flattened side of the LED base) into the adjacent ground (Gnd) pin on the Arduino

## Connect the buzzer's red wire to the Arduino's digital pin 10. Connect the buzzer's black wire to the Arduino's Gnd pin (there's a spare one on the Power block of pins). NOTE: These two wires can be reversed, as the polarity of the buzzer doesn't matter.

## Launch the Arduino IDE software then plug the USB cable into your computer and Arduino. Set the board and port settings for your Arduino board, in this case, an Arduino Uno. Open the PIR Alarm sketch found at this link: https://gist.github.com/opethe1st/10490989 (Arduino programs are called sketches.) Upload the sketch to the Arduino.

notes: 

## When you power up your alarm, the PIR sensor will glow an ominous red. Stand very still or leave the room while the alarm calibrates the infrared level reading for the room. Now test it by moving: the buzzer will buzz and the LED will light up. Be amazed! Your PIR Sensor Arduino Alarm can sense movement up to 20 feet away. No one will be stealing your yo-yo today. NOTE: Might not be reliable for detecting the undead.
