Computers and control
Convenor: Peter Normington
This friendly and supportive group started in September 2018, taking forward ideas and suggestions offered by members of the 2017/18 group Logic, mathematical reasoning and programming in Haskell.
The aim of the group is to explore topics in computing and electronics, based largely on the Raspberry Pi, a single-board computer, and the Arduino, a programmable microcontroller. It is very much a hands-on approach: during the first few weeks of last year all members acquired a Raspberry Pi and most use their own laptop to operate their own (and others') remotely.
Members of the group learn about programming, using shell scripts and Python3, client-server computing and networking. Since this is a continuation group, all members now have some familiarity with the Linux command line and filesystem. We have used attached electronic components and other hardware to sense, control and display, including humidity and temperature sensing, control of LED arrays and RFID card reading and writing. In general, we follow topics of interest as they emerge.
The meetings have been held weekly, on Monday mornings for two hours from 10.30 am, except for those occasions (usually the second Monday of the month) when the Skiddaw U3A Popular Science group meets. However, since the meeting of 16th March 2020, as a precaution during the COVID-19 pandemic, we have decided to hold "virtual meetings" using videoconferencing software.
At this stage we are therefore unable to accept new members. If you are interested in joining at some point in the future, please contact the convenor using the form on this website.
