Week 2 welcome

James outlines this weeks activities and the learning objectives you will cover.
4.1
Hi. Welcome back. In last week’s activities, you set up your Raspberry Pi and wrote your first Python programme. This week, you’re going to get physical. You’ll learn all about the GPIO pins on your Raspberry Pi and how they can be connected to real-world devices. You’ll build a circuit using an LED and switch it on and off using some Python code. Once you control an LED, you’ll be able to create light sequences with multiple LEDs or broadcast messages using Morse code. It’s been great to see so many of you sharing and discussing your learning from week one. There are many more opportunities to do the same thing this week, and we look forward to hearing from you all.

In Week 1, you learned how to set up the Raspberry Pi, and wrote your first few lines of code in Python. You also looked at how the Raspberry Pi can facilitate teaching Physical Computing to your students.

This week you’ll be getting physical with the Raspberry Pi, using it to control a simple circuit that you can build in minutes.

Remember that throughout the course you can join in the discussions at the bottom of each learning step. Why not post a question if you need a bit of help with a concept, or take a shot at answering another student’s question? As you know, teaching others reinforces what you’re learning, and you might pick up some new information too!

This week you will:

  • Learn about the GPIO pins on the Raspberry Pi and how they can be connected to real world devices.
  • Build a circuit featuring an LED and switch it on and off using some Python code.
  • Create light sequences using multiple LEDs or broadcast encoded messages using LED flashes.

Do you have previous experience of using or teaching simple electronics? If so, please tell us about it in the comments below.
