Make your E-Ink display into a name and info badge about yourself 😃
E-ink, also known as “electronic ink” or “electronic paper,” is a type of display technology known for its low power consumption and visual similarity to ink on paper. These features make it a perfect fit for e-readers such as the Amazon Kindle and also for E-Ink price tags that display information about products on supermarket shelves.
With e-ink technology, tiny microcapsules are suspended in a liquid that is inside a very thin layer. The microcapsules, which are roughly the width of a human hair, contain positively charged white particles and negatively charged black particles.
Applying a negative electrical field causes the white particles to rise to the surface. Conversely, applying a positive electrical field causes the black particles to rise to the surface. By applying different fields at different parts of a screen, e-ink produces a text display.

Let's create a project to make our e-ink display into a name badge that displays some different information about us.
Create a new Microbit project.
To access the blocks we need to program the e-ink display, you need to add the inkybit extension to your project.
To add an extension follow these steps:
Let's program the A button to display your name.
Add the following code to your project. The code will:
