Demonstration of the the two initial models Raspberry Pi (A and B), the different connectors, adding memory and power, and switching on your Raspberry Pi.

Before you watch this, we recommend you watch the first tutorial: ‘Flowcharting 1: decisions, processing and looping’. In this second tutorial, we will extend the basic ideas of flowcharting to incorporate the use of variables, and carry out a ‘dry run’ of our application.

In this tutorial we will introduce you to the basic ideas of flowcharting. To get you used to the idea, take a look at the video showing a simple scenario of a monkey in the jungle who gets hungry. Now watch the next tutorial: ‘Flowcharting 2: using variables’.
