Topic or title of your lightning talk *
We would like you to propose a 5 minute talk/presentation or 30 min workshop for our next #RJam. The talk can be on anything you think the audience will find interesting, informative, educational related to technology, computers, Microbit, Raspberry Pi, hardware, software - but DOES NOT have to be your own work, it could be something you have heard about, seen, read, a project, a product review, an experience, a tutorial, an article in MagPi or micro:mag etc. Ask for help if you're looking for ideas.
