Adding Arduino based alarm system

[jaivsh]

Describe the project you want to add with tech stack

I'd add the arduino code for alarm system. This code would work along with the following hardware:

• 1 x Ultrasonic "ping" sensor
• 1 x Piezo buzzer
• 1 x LED strip light

It would make an alarm if an intruder crosses it's limit lines.

Expected behavior

• User puts the code into the microcontroller through Arduino IDE
• Microcontroller, which is already connected to hardware, starts operating
• It blinks green light/sound depending on type of signal device used.
• If there is intrusion, it blinks red/alarm tone.
