In this post I’ll be covering fundamental electronic signals. These will establish a foundation for us to work from as I begin to cover more advanced signaling technology. First, we will cover digital signals. These are the most basic since they are either on or off. Next, we cover RC Time circuits which allow us to use a digital port to read an analog condition. We’ll follow that up with analog signals and how we read them electronically. Next, I’ll…
Now I would like to return back to home automation and control. There are basically three components of the system; these are input devices, controllers, and output devices. Lets start by covering the heart of the system, the controllers. In this section I’ll cover the controllers. They fall into three categories, device, communications, and central. The central controller will be the Raspberry Pi. It is Rome and all roads lead to it. It takes input, produces output, and is what…
Back in 1993, while in college, I purchased an Intel 486 computer. The intent was to save me the hassles of the computer lab. It was extremely convenient to be able to do my work on my schedule. As a consequence, I tinkered with the PC in my spare time. I had created the DOS 6.x / Windows 3.x install disk sets, at the suggestion of the sales agent. I eventually needed them. Breaking and rebuilding was a clumsy cycle…
