DIY mobile phone – Create your own mobile phone

This DIY cell phone created at MIT manages to have something for just about every major contemporary subculture or hipster subset I can think of. Nerds and tinkerers? Check. Wooden case for the steampunk set? Check. Huge antenna for the retro, skinny-jeans-wearing set? Check. Big buttons for the fat-thumbed and Luddite crowd? Check. Rugged design for outdoorsy types? Check. The folks at the MIT Media Lab cr ...

SMS control 4 way remote control relays using ATtiny2313 microcontroller

Introduction   With this circuit we can control up to 8 devices (4 devices in our example project), by sending a specific SMS message with any mobile phone. It's very useful in the case that, at the place we have the devices, we have not a wired (fixed) telephone line. If you have an old ericsson mobile phone and you are not using it, its the time to build some useful with that.  The controlling that w ...

SMS Based Voting System – AVR GSM Project using ATmega32 microcontroller

Hi friends ! Here I am showing a microcontroller based project called the "GSM Based Voting System". Using this system you can ask your users to vote for any of the four options. Four available options are identified by a letters 'A', 'B', 'C' and 'D'. User can vote for any option by sending a text message to the mobile number. For example if you want to create a poll like this. Which is your favorite phone ...

AVR Based Mobile Phone using AVR ATmega128A microcontroller

AvrPhone is ATmega128A-based simple mobile phone with touch screen and SIM100S GSM module. The display uses 2,4″ LCD with a resistive touch screen and ILI9325B driver (16 bit parallel bus). The LCD breakout board contains SD card slot and XPT2046 touchscreen controller. They both are connected to AVR’s SPI bus. The project is powered by 3.7V/1000mAh Li-Po cell. The user interface provides way to make and re ...

Advance Fire Alarm through Mobile Phone using microcontroller

An automatic fire  alarm system is designed to detect  the unwanted presence  of  fire  by monitoring  environmental  changes  associated  with combustion.  In  general,  a  fire alarm  system  is  classified  as  either automatically  actuated,  manually  actuated,  or both. Automatic  fire  alarm systems  are  intended  to  notify  the  building  occupants  to  evacuate  in  the event  of  a  fire  or  ot ...

Cellphone controlled robot vehicle using ATmega16 microcontroller

When we talk about wireless robot vehicles, we usually think about the RF circuits. But this project is different. It uses a mobile phone to control the motion of a robotic vehicle, and therefore, the range of operation is as large as the coverage area of the service provider. The project is based on an ATmega16 microcontroller that is interfaced to the mobile phone through a MT8870 IC, which is a DTMF to B ...
