Arduino Security System

A security system that uses a variety of sensors to detect if a person is near, sound an alarm, send a message through the LCD, and light up the LEDS.

Features

• Fully Working LiquidCrystal LCD
• Motion Detection
• Sound Output

How To Make

Required Parts

• 1x | Liquid Crystal LCD
• 2x | LEDs
• 4x | 22Ω Resisters
• 48x¹ | Wires
• 1x | UltraSonic Sensor
• 1x | Potentiometer 500Ω
• 1x | Piezo Speaker
• 2x | Bread Board
• 1x | Arduino²

Building

While there is no specific way to build it (just follow the diagram, it's accurate and easy to understand), its easier to start with building everything on the bread board, then adding the wires to the Arduino, then adding the ultrasonic sensor to everything.

Code

Download the Code from the repo or in the Releases tab, open it in Arduino IDE, plug-in and select your Arduino. Click serial monitor, and watch it run. If it doesn't run or doesn't run right, then check your connections and check if you placed something in the incorrect slot. If all goes wrong, check the code and tailor it to your project.

¹ Estimate Number, you'll probably need more or less

² You can use any Arduino, I used an Arduino Uno Wifi Rev2
