Line follower Robot is a machine which follows a line, either a black line or white line. Basically there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line. Line follower actually senses the line and run over it.

Making a plant sing has been a trick since the Theremin was invented. Here I am going to teach you how to do this with and arduino board, a gameduino shield and a the touch shield from my previous instructable.

The E.L.F. robot dances to the beat of any song it hears. One of the coolest things about this project is that its creator, John Jensen, had no previous hardware building experience prior to this project. This quick learner made the SpiderBot while deployed to Iraq. He chose the BeagleBoard to give the spider plenty of speed and well-defined dance moves.

In this tutorial we will see how to use WhatsApp with Raspberry Pi.We will use the Yowsup library we had already used in these tutorials: WhatsApp message from Phidgets SBC , Phidgets WhatsApp - ask the status of your sensors.Yowsup is a python library that allows you to login and use the WhatsApp service .

My motivation for this project was to minimize the usage of functions such as _delay_ms(), _delay_us() and their derivatives with some exceptions, like delays to control the LCD.

Delay pauses the whole program, so if one is using delay for 10 seconds everything will pause for those 10 seconds, therefore nothing can be done in those 10 seconds.
