(6)Test Result
After uploading test code to micro:bit main board and powering the main
board via the USB cable, the LED in (1,0) lights up for 1s and the one in (3,4)
shines for 1s and repeat this sequence.

Project 3: LED Dot Matrix

(1) Project Introduction
Dot matrices are very commonplace in daily life. They have found wide
applications in LED advertisement screens, elevator floor display, bus stop
announcement and so on.
The LED dot matrix of Micro: Bit main board contains 25 LEDs in a grid.
Previously, we have succeeded in controlling a certain LED to light by
integrating its position value into the test code. Supported by the same
theory, we can turn on many LEDs at the same time to showcase patterns,
digits and characters.
What's more, we can also click"show icon" to choose the pattern we like
to display. Last but not the least, we can design patterns by ourselves as
well.
