[ Arduino ] how to tweet with arduino

 

For other  interesting ARDUINO PROJECTS here

An Arduino sending tweets? Absolutely! Darren Yates shows you how to get your Arduino its own Twitter account and tweeting automatically.

Our Twitter weather station needs no soldering and uses just three parts — build it for under $30.

From many people I’ve talked to, Twitter is one of those things you either love or hate. Even so, its hundreds of millions of devotees make it as key to the internet as Facebook or YouTube. If selfies from C-grade celebrities tweeting what they’re eating or wearing isn’t doing it for you, how about putting it to better use — with your Arduino? Yep, you can connect your Arduino directly to Twitter and have your microcontroller automatically send tweets that you can monitor on any Twitter client. All of a sudden, Arduino and Twitter becomes a combination full of possibilities.

How Silicon makes a Solar Cell

How Silicon makes a Solar Cell

Silicon has some special chemical properties, especially in its crystalline form.
An atom of silicon has 14 electrons, arranged in three different shells. The first two shells
which hold two and eight electrons respectively are completely full. The outer shell, however,
is only half full with just four electrons. A silicon atom will always look for ways to fill up its
last shell, and to do this, it will share electrons with four nearby atoms. It's like each atom
holds hands with its neighbors, except that in this case, each atom has four hands joined to
four neighbors. That's what forms the crystalline structure, and that structure turns out to be
important to this type of PV cell.

A Change to Google Code Download Service

Project Hosting on Google Code provides a free collaborative development environment for open source projects. Each project comes with its own member controls, Subversion/Mercurial/Git repository, issue tracker, wiki pages, and downloads service.

Downloads were implemented by Project Hosting on Google Code to enable open source projects to make their files available for public download. Unfortunately, downloads have become a source of abuse with a significant increase in incidents recently. Due to this increasing misuse of the service and a desire to keep our community safe and secure, we are deprecating downloads.

Starting today, existing projects that do not have any downloads and all new projects will not have the ability to create downloads. Existing projects with downloads will see no visible changes until January 14, 2014 and will no longer have the ability to create new downloads starting on January 15, 2014.  All existing downloads in these projects will continue to be accessible for the foreseeable future.

If your project is using downloads to host and distribute files and has a need to periodically create new downloads, we recommend you move your downloads to an alternate service like Google Drive before January 15, 2014. If you choose to move your files to Google Drive, check out our help article.
