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.
- Fully Working LiquidCrystal LCD
- Motion Detection
- Sound Output
- 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
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.
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; check if you placed something wrong; and if all goes wrong, check the code and tailor it to what you need, its fully commented so you'll know what each part means.

1 Estimate Number, you'll probably need more or less
2 You can use any Arduino, I used an Arduino Uno Wifi Rev2
