Many people will disagree with me when I say the cloud is just a server. Clouds can be classified as public, private or hybrid, but that is what it really boils down to it is a machine or set of machines providing services over the web. Certainly you can argue that cloud can provide infrastructure, platform, and the traditional application services. Talked about some of these services in earlier articles. However the internet is a network of systems that can be clearly defined. In the systems on the network can be described sort of like a road map or a set of telephone lines connected like below. It may not be important exactly how they are put together, except that we know they are there. To know who is where either by what is known as a web address or an ipaddress (sort of phone number) allows you to access part of the cloud that you wish to connect to. It is impossible to know every phone number or ipaddress by heart, so the internet has a built in phonebook known as a Domain name s...

It's almost the holiday season and you might want to get geekie. If you are unsure about this, get profession help for the project. Try this at your own risk. We take no responsibilities for anything you may or may not do. This article is not a how to, but it is informational. What we want to do is to control lighting so that we can turn it off or on with electronic equipment instead of doing it manually with a traditional light switch. In this case, we may want to control holiday lights Such as an Xmas tree. We could use the light switch like above, or we can use a computer or a micro-controller. In this case we will suggest three posiblilities. The computer using a traditional parallel port, A raspberry Pi, or an Arduino. The simplest way to do this is with a solid state relay. Basically it is just like turning on an led. If you turn on the data line so it goes to near 5 volts, the led will turn on  or the SSR will allow the output side to work. An SSR let y...
