The Raspberry Pi has 30 GPIO pins, but none of them are analogue inputs. At this meeting, we’ll take a deeper look at how to take an analogue signal (like temperature) and connect it to the Pi, and access it via Python.
The Internet of Things (IoT) is a hot topic. Join us, as we continue to explore the vast world of IoT using the Raspberry Pi. This weeks session will focus on IoT devices streaming data over the internet.

Python provides for the raising and handling of exceptions. An exception is used primarily for managing an error situation but is also handy in other circumstances e.g. an exception is used internally to end loop iteration.
A full writeup for this session is available here.
It’s been a while so first a short(ish) recap of the previous 3 presentations, including in more detail the Input And Output section of session 3. Then I’ll discuss some useful Python Tutorials. And finally, we can go on to cover some further aspects of the language.
Tired of iTunes? Time for PiTunes! — HiFi audio from your Pi.
You don’t need a PC or laptop to enjoy listening to hifi audio from your personal collection or Internet streaming. And you won’t have to endure the convoluted iTunes interface.
A low-cost Digital Audio Converter (DAC) or DAC and Amplifier such as offered by HiFiBerry or IQAudio will turn any Raspberry Pi2 or 3 into a low-cost and energy-efficient MPD audio server controlled from a Web browser or an iOS/Android app.
Join us as instructor Stuart Hertzog explains how to set up a DAC on your Pi and demonstrates the free and open-source Linux audio software PiMusicBox, Volumio, RuneAudio, and MoOde Audio.
Discover PiFi audio and a world of listening pleasure!
This meeting we’ll pick up on the Pi GPIO pins (Part 2), looking at input, using switches (push buttons). You’ll learn how to not only have your Pi illuminate lights or close relays, but also to take input via GPIO. Using the input and output GPIO capabilities of the Pi, one can create a home automation system, or even replace your “Nest” thermostat with the Pi.
Bring your Pi and get hands on help after the presentation.
Instructor Simon Bluck continues his popular Learning Python series, this time with an in-depth look into functions. Invaluable to people who are just getting into or who wish to deepen their understanding of this popular programming language.

Last March Break, I read a book that changed my life. I immediately ran out and purchased an Arduino. A Raspberry Pi was not far behind. After a few months of experimenting, and watching YouTube videos of kids building Obstacle Avoidance Robots (OAR), we thought it looked like a good ﬁrst project. We call it Bobby OAR. An OAR is an autonomous robot that rolls around and avoids obstacles by using sensor input. Then, based on programming, ﬁnds an alternate path forward, avoiding obstacles along the way. We had most of the components from various kits, so only a chassis and wheels needed to be ordered. Or was there something else?
This Python Course covers what is useful to know so you can quickly and easily set about writing Python programs. (Detailed Python programming will be covered in subsequent courses.) This course is suitable for anyone, from those that may have very little computing/programming experience, to those who have already been actively programming in Python. The aim is to get everyone up to the point where they feel confident in using Python and writing useful programs.
One of the many cool things you can do with your Raspberry Pi is to add a special $30 DVT-T USB dongle and install some software to turn your Pi into a live flight data feeder for FlightRadar24.com and FlightAware.com.
Among the benefits of this project are gaining free premium memberships with both sites; the ability to monitor flights overhead in real-time; and learing a bit about how to install third-party software via the command line.
In this presentation, I will give an overview of the hardare and software required and perform a quick walk-through installing the FlightRadar24.com feeder. If time permits, I will also demonstrate installing the FlightAware.com feeder.
Since these feeder stations are location-dependent, you will have to perform your own install at the place from which you’ll set up your Pi feeder and antenna.
