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 – tag…you’re it There are 10 weeks left and they’ll go by fast, so we’re going to be moving quick through a lot of material. This post will be on geotagging. We’ll be tagging Accelerometer data along with current usage for use in heat maps hosted by CartoDB. If you haven’t used CartoDB, create an account and take a look at the tutorials they offer. Once you have a bit of background, come on back. Purpose – one slice…
