Recently I started to run low on space so I decided to buy a new hard drive and although the speed increase from the faster drive was a nice bonus I still felt like something was missing, oh thats right an HD ACTIVITY LIGHT APPLE! I can see Steve Jobs making this call while saying something along the lines of it distracting from the cleanliness of the design and he probably called it an obsolete feature stating most disks are constantly active with modern search indexing and background tasks blah blah, I obviously don’t agree with this and many others don’t agree either. Even if I didn’t find this useful in OSX I do dual boot Windows and sometimes I find myself saying “what the hell is this thing doing”, its nice to know if it is doing something or if the OS is hung up on a task. Anyway enough ranting let’s get into the mod. I wanted to keep everything stock looking so I needed a place to put the LED where it
Arduino – Interrupt Tutorial with LED & Switch
Well well well, Look who’s back for more already. If you’re pushing through these Arduino tutorials screaming give me more then I’d like to be the first to tell you good job and keep it up. Soon you will have this thing called the Arduino mastered and that creation that you had in mind (The one that got you into this mess in the first place) will seem like child’s play once I’m through with you. So throw on another pot of coffee and indulge in whatever other vexes you may have because its 4AM here near Detroit Michigan and I am right there going strong with you. OK so in order to be here you should have already read the first LED tutorial entitled Advanced LED Blink. That tutorial will give you the background on this tutorial and will also help you get started into Arduino’s. So where we left off previously is that we had a working LED blink circuit that was triggered by a momentary push button, the problem was that once
Arduino – Advanced LED Blink
By now you should have your Arduino and have gone through the Arduino Website and maybe you received some documentation with your board which describes the Electrical Engineering Hello World, The LED Blink Sketch. The LED Blink sketch gives you a rough idea of how you will send commands to the micro controller and how the micro controller will communicate with components attached to it. Other than that your pretty much on your own, if you have a background in software programming, especially C, C++ or C#, you will be able to pick up on most of this very quickly. There are some components which take thorough explanation on how they operate but other than that its mostly all in the code. I plan to write several articles and in each one I will cover a circuit, the components and the code. I will introduce and explain components, concepts and code in each one. This first one is the Blink Sketch with a twist and the first thing you will notice is one part needs some explanation as to why its there
