A Raspberry Pi is a credit card-sized computer originally designed for education, inspired by the 1981 BBC Micro. Creator Eben Upton’s goal was to create a low-cost device that would improve programming skills and hardware understanding at the pre-university level. But thanks to its small size and accessible price, it was quickly adopted by tinkerers, makers, and electronics enthusiasts for projects that require more than a basic microcontroller (such as Arduino devices)

The Raspberry Pi is slower than a modern laptop or desktop but is still a complete Linux computer and can provide all the expected abilities that implies, at a low-power consumption level.

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.

This tutorial will show how to build a simple voice controlled robot that’s easy enough for beginners to make in just a few hours. I show how it can be done in two languages, both English and Thai.
The cost of the entire project is about ~$224, which factors in quality components and parts.

There will be three parts to this tutorial. This part will show you how to assemble the robot mechanically, the next part will show you how to program your microcontroller, and the last part will be how to configure voice recognition.

Every year about 700,000 vehicles get stolen in US. In fact, a car is stolen every 45 seconds.

We all love our cars and whether it is a roaring Lamborghini or a purring Prius, we are attached to it and wish that it never gets stolen.

I am very attached to my family car and take lots of precaution that I do not park my car in secluded places or double check that I always lock my car when I park it anywhere and always carry my car keys with me. 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.
