lesson 5

personal billboard

select different images and messages when code is running

scroll through text messages

show images that match your current mood

lesson 4

Heart Beat

make the heartbeat speed adjustable using the microbit buttons

A = slower B =faster

make code loop forever

code an animated heartbeat

program push-button to make a fast click game

crunch some numbers with a micro-calculator

display text message strings

change the animation speed of the images

show a sequence of images on the display

from microbit import * display.show(Image.SQUARE)

lesson 1

called first steps

what is a microbit?

static electricity

senosors and buttons and an LED display for output

edge connector

a powerful embedded computer

Python

conditions

Booleans variables

Tracy

while loops

To repeat code when the number of times to repeat is unknown

if statements

!=

To have Tracy make decisions based on conditional statements

if count > 0: pendown()

parameters

tailor functions to be used in multiple situations

many times

user input

radius = int(input(“What is the radius?: “))

variables

Store information to use in our code

Top down design

Separating a large problems into smaller ones

Writing code for one part of a function before tackling the whole thing

breaks large code into functions

Breaking the problem down into smaller parts

artistic effect

begin_fill() circle(20) end_fill()

color must be in quation marks

functions

three_circles()

A function name and commands to be performed

one command

naming guidelines

make_sqaure

draw_square

comments

# used in the beginning of a comment

""" for a multi-line comment

allowing humans to read and understand

turning angles

right(180)

setposition()

speed 0

loops

write the same code with fewer lines

makes code easier to read

for i in range ()

penup commands

pendown commands

400 pixels by 400 pixels

starts at the bottom

(0,0)

east

circle commands

diameter when coding

200 pixels from starting point

left or right commands

forward input

forward (-100)

forward (100)

Printing

To print non-text, do the same as text but don't use quotation marks

To print text, do print "enter text here"

Comments

Do # enter comment here to do a single line comment

Do """ enter comment here """ to do a multiline comment

Operators

Rounding, round(x, number of digits to round by)

Power, math.pow(x,y)

Absolute value, abs(x)

Modulus, do x % y

Division, do x / y

Multiplication, do x * y

Subtraction, do x - y

Addition, use x + y

User Input

For numbers, do variable_name = int(input("Enter value here "))

For strings, do variable_name = input("Enter text here ")

Variables

variable_name = value

variable_name = "enter string"

Used to store and edit values later

Web design and development

the ability to understand what is needed to make a website functional and easy to use, but at the same time make it aesthetically appealing to the user.

build the backbone of websites, typically from the ground up, and knows languages specific to the web.
