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.

Beagleboard based Dancing SpiderBot
http://www.eetimes.com –
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.

Arduino Based Garage Door Opener
http://www.megunolink.com –
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.

LED Interfacing with 8051 Microcontroller
http://circuitdigest.com –
LED interfacing is the first thing, one would try to do while getting started with any microcontroller. So here in this tutorial we are going to interface a LED with 8051 microcontroller, and will write a C Program to blink the LED. We have used a very popular microcontroller AT89S52, of 8051 family, by ATMEL.

Threading and Timers in Atmega328p
http://www.engineersgarage.com –
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.

USING AN AVR AS AN RFID TAG
http://scanlime.org –
Last time, I posted an ultra-simple “from scratch” RFID reader, which uses no application-specific components: just a Propeller microcontroller and a few passive components. This time, I tried the opposite: building an RFID tag using no application-specific parts.
