# Coordinate grid and LEDs
|
||
|
|
|
||
|
|
This lesson introduces the use of coordinates to store data or the results of mathematical operations. It gives students practice programming for the LEDs of the micro:bit screen using coordinates. And introduces the basic game blocks of MakeCode.
|
||
|
|
|
||
|
|
## Lesson objectives
|
||
|
|
|
||
|
|
Students will...
|
||
|
|
* Understand that the 5 x 5 grid of LEDs on the micro:bit represent a coordinate grid with the origin (0,0) in the top left corner.
|
||
|
|
* Understand that the values of the x coordinates range from 0 through four and increase from left to right.
|
||
|
|
* Understand that the values of the y coordinates range from 0 through four and increase from top to bottom.
|
||
|
|
* Learn how to refer to an individual LED by its x & y coordinates.
|
||
|
|
* Learn how to plot (turn on) and unplot (turn off) individual LEDs and how to toggle between these two states.
|
||
|
|
* Learn how to check the current on or off status of an individual LED as well as check and set the brightness level.
|
||
|
|
* Apply the above knowledge and skills to create a unique program that uses coordinates as an integral part of the program.
