Hi again everyone.

This week we started looking at physical computing and the Raspberry Pi. This involves attaching various components such as sensors, motors or controllers to the GPIO pins on our Pi. This week we connected a LED and two buttons, and we used the GPIO Zero module for Python to control them. I’ve made a video, it’s a little bit long, that covers everything from Saturday’s session.

At the end of the session the group started working on a traffic light idea and we will combine this with HC-SR04 ultrasonic distance sensor next week to create a measuring device.

I don’t have any slides this week as we worked directly from the GPIO Zero Documentation available at https://gpiozero.readthedocs.io. This is also available on Dropbox, along with this week’s code and a sheet that contains a drawing of our circuit and drawing of the GPIO pin layout, here: https://www.dropbox.com/sh/k26mbrfmdvq9tro/AAB5jfjkIlBqLhfnUAVVUvtJa?dl=0.

See you all next Saturday.

Declan, Dave and Alaidh.
