CSE Day 2 - Variables & While

Wednesday, Sept. 25th

We can store a value (number, text, etc) in a container called a variable

These are just like variables in math class: x = 5 or message = "Hello"
We can then use and modify these variables to accomplish certain goals:
u.set_pixel(x_coord, y_coord, 200, 0, 0)

We also learned that we can use a variable to repeat code a certain number of times using the while loop.

Turn on a single line of white lights:

import unicornhathd as u

x = 0

while x < 16:
u.set_pixel(x, 0, 255, 255, 255)
x = x + 1

u.show()
