A2. How do they enhance teaching and learning

Unicorn hat
Design, awe and wonder, coordinates, relatively simple Python API

Pibrella - 
Simple way to power motors, very simple traffic lights, simple connectivity of switches, demonstration of input and output in one simple device

Explorer hat - 
input and outputs, ability to build simple prototypes, touch buttons can easily be used as inputs

A3

A3. Barriers to using as a whole class

Unicorn hat - cost, potential eye damage if on 100%, can take a long time to code individual pixels

Pibrella - they are becoming scarce and harder to find

Explorer hat - cost

All three require downloads so will need additional time with Internet connection to update.

A4

A4. How do you know which ones to try?

Look for other projects and resources which people have used

Start with a project idea and then research the accessory
Buy a range of accessories rather than lots of one
