What is Arduino?

Arduino is a single-board microcontroller, intended to make the application of interactive objects or environments more accessible.[1] The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. Current models feature a USB interface, 6 analog input pins, as well as 14 digital I/O pins which allows the user to attach various extension boards.

Before we can fully understand what Arduino is, it’s important to realize what it isn’t. An Arduino is not a computer (the way Raspberry Pi is). It can’t be programmed independently; it needs to be plugged into a computer. It is not especially powerful either—the Arduino Uno has 32 KG of memory, while the average Macbook has about 8 gigs.

However, I am still worried whether my car is safe. In order to get rid of these genuine worries, I decided to design my own low cost car tracking system.
