Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. It can also display some character alphabets like A,B,C,H,F,E etc. In this tutorial, we are going to learn how to interface a segment with 8051 microcontroller. We are using AT89S52 microcontroller.

A Gesture Controlled robot is a kind of robot which can be controlled by your hand gestures not by old buttons.You just need to wear a small transmitting device in your hand which included an acceleration meter. This will transmit an appropriate command to the robot so that it can do whatever we want.

For my second real project for the Raspberry Pi I needed it to be something that took advantage of the recently released Raspberry Pi Camera Board. My idea was to make an extremely simple “point and shoot” camera. I wanted it to be able to run on batteries, connect over Wifi and have as much of the project inside of the original box as I could.

We can divide this arduino based thermometer project into three sections - one senses the temperature by using temperature sensor LM 35, second section converts the temperature value into a suitable numbers in Celsius scale which is done by Arduino, and last part of system displays temperature on LCD.

Getting stuck out in the rain without keys was the motivation for this project. It lets you trigger a garage door opener through a website hosted by an Arduino. With the Arduino connected to a wireless network, you can use your smart phone to connect to the webserver, enter a password, activate the garage door and get inside before getting drenched in the downpour.
