Door-Alarm-System

This is a Door Alarm System Project made using aurdino And reed Switch with the help of IOT.

Schematics

Below are the schematics provided for the code above.

Components Needed

Arduino uno
Magnetic Contact Switch - Door Sensor
Buzzer
Breadboard and some cable

Magnetic Door Sensor (Reed Switch):

Since the switch is non polar, you can plug in the wires any way.
Connect one wire of the switch to a jumper wire and plug the jumper wire pin to pin GND on the POWER side of the Arduino
Connect the other switch wire to another jumper wire, and plug that jumper wire into pin 4 of the Arduino.
