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…
Introduction – over the garden wall In mid July of 2014, I had posted about a new version of RPi and XBee. In this post will cover XBee wireless technology. We will also cover how XBee can be used to link sensors to the RPi. Next, we go through linking the Arduino to the RPi. In reminiscence, a newer offering of the RPi has just been made available to the public. I may do a brief overview of the new features,…
