In the past week of Geometry, I have been learning/experimenting with a LED grid. I have created a few codes that are open for use. Here is a GitHub link with what I have done so far.
The LEDs on the grid go in a back-and-forth pattern.Once I figured out how to light up one LED, I boiled down the code to one number and compared it to the code of the light next to it. Then after finding the appropriate code for a longer line, I compared it to a line next to it. The graph represents those two lines. I found the equation for both lines and used them to make a function where I can light up any LED with its coordinates. Then I made a grid in my code so that all I have to do is type the first letter of color in the exact spot on the digital grid and physical grid, and it will light up. The code is all set up so that any of the students can display whatever design they chose.
