Getting ready for Christmas with SMS controlled lights

Christmas is nearing and we start thinking of decorations and lighting projects. There are tons of choices what to use. But if you want something more, then try adding something your own like remote control for Christmas lights. By following an instructable you will be able to build an SMS controlled lights. The idea was to use Arduino Yun, protoshield with small breadboard, a 5V relay, buzzer and few other small things. Relay is simply attached to light controller button circuit so it could take over with Arduino control signal. Arduino Yun is used to connect to internet of things website called Temboo. It allows setting up remote services where you can send messages and so pass parameters to Arduino and from it. Once set you can start sending SMS messages like “Lights on” or “Lights off” and this way switch or toggle light effects. Each control is followed by audible alarm from piezo buzzer. Of course you can extend this project by adding more light circuits or give more switching options as you like. Continue reading

Atmega8 based GSP alerter through SMS

Alex had previous experience with his GPS logger, so recently he decided to build another project called GPS alerter which would send SMS when device is located in a certain area. Device also is equipped with accelerometer which allows detecting movement, so it could activate GPS module and start getting data. This helps to preserve battery life as there is no need to check coordinates while it is at same coordinates. [youtube  https://www.youtube.com/watch?v=JNAqu732Uqw&w=468] For this project he uses Atmega8 microcontroller which read GPS data through serial port. To send SMS messages there is an old Nokia 3210 cell phone used which is fairly easy to interface. Continue reading

Apply the 3R Concept with Your Old Personal GSM Phone

Do you love to follow the latest trend of cell phones? If you answered yes, then I’m bet you might have at least one old GSM Phone, which had been left in drawer for years. Since you’re not anymore using it, why don’t show off your credibility and creativity in the renovation field? This simply an easy task, where you just need to apply the PIC microcontroller and connect it with your Ericsson T18 series phone (You can also test this stuff with the A1018 and T28 series as well). This method only good for own personal use, if you want it to be commercialized, it’s meet the difficulty of finding the suitable connectors in large amount (Go on and try to commercialize it if you did found a good supplier, which can provide you those needed connectors in low price). The objective for this project is to remote activated or receiving SMS in alarm case. Therefore, this GSM2 has transformed into a multipurpose gadget (bidirectional GSM Remote Control – remote activator – receiver of SMS alarms) now. Don’t just… Continue reading
