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.
This session adds to what was learnt from Session 2: Syntax and Constructs, and goes on to cover some further language constructs. The sessions now broadly follow the standard tutorial, but in a very condensed way. You are very much advised to refer to the tutorial for a fuller coverage of the language; and indeed, to the full language reference for complete coverage. Some of the examples shown here are taken from the tutorial.

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?
