I love electronics, gadgets, robots and anything that is moved by a 12v battery. Before I became a programmer this was my passion. I like dissecting my battery-powered toys and take their heart off and feed them to the dogs lol, kidding aside, I'm just passionately curious how stuff works.
OK! Enough chitchat. This is my first electronic project using an UNO Rev3 and a GSM Shield both manufactured by Arduino. Arduino started in 2005 as a project for students at the Design Institute of Ivrea, Italy. Basically, Arduino is a single-board microcontroller designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. All their hardware are open source that's why you can easily understand how does it works, well, that is if you're really into electronics. But you don't don't have to be that geeky to use Arduino even enthusiast(like me) can use it just few basic knowledge with programming and wiring stuff and you're good to go. And you're always free to drop by in their forum other users will gladly help you in case you have a problem.
My project is a mobile Phonebooth which can be used by dropping coins minimum of Php10 and you can call for about 3-5mins not yet sure. Currently it is still a work in progress and still have plenty of things to be done but I already finished coding the voice call, coin sensor and lcd display (though I can't clear the screen yet lol). I'll be posting picture updates in this site for you to see the progress and the source code of course when it's finished.
