What is a resistor?
type of wire
resists the flow of electricity, two types 330 Ohm and 10k Ohm
controls the flow of electricity and only allows it to flow one direction
a type of LED
What is a servo?
a piece of hardware that turns a device a certain angle and holds it there
writes angles from 0 to 180
none of these choices
a piece of hardware that needs three wires, one for ground pin, power pin and PWM pin
What is a possible digital signal state?
0
0 - 255
255
HIGH
What is the value for an analogRead( ) signal that is all the way on?
0
1023
LOW
255
analogWrite( ) can write a value between:
0 - 1023
0 - 255
255 - 1023
1023
A photo resistor is:
an analog sensor that measures ambient light and returns a value between 0 and 255
a digital sensor that measures ambient light and returns a value between 0 and 255
an analog sensor that measures ambient light and returns a value between 0 and 1023
a digital sensor that measures ambient light and returns and a value between 0 and 1023
When using the scratch program, what does this block do?
reads a statement and executes the statement if true
reads a statement and repeats the statement in a forever loop
reads a statement and executes the statement if false
reads the program and pauses the program
While using the scratch program, what does this block do?
reads a statement and executes the statement if true
reads a statement and repeats the statement in a forever loop
reads a statement and executes the statement if false
reads a statement and pauses the program
While using the scratch program, what does this block do?
reads a statement and executes the statement if true
reads a statement and executes the statement if false
reads the statement and repeats the statement in a forever loop
reads the statement and pauses the program for one second
Which block will run a program, check all that apply
What will this code do?
start the program and the sprite will forever follow the mouse-pointer
end the program and the cursor follows the arrow on the screen
start the program and the cursor will forever follow the mouse-pointer
end the program and the cursor jumps from sprite to sprite
This code will:
run when the space bar is pressed, the sprite will forever turn counterclockwise 15 degrees and then 10 steps 10 times
do nothing there is no start command
run when the space bar is pressed, the sprite will move 10 steps, 10 times, and forever turn counterclockwise 15 degrees
run when the space bar is pressed, and alternate between moving 10 steps and rotating counterclockwise
If we want a condition to be checked an infinite number of times we must use a
If statement
Forever Loop
Repeat Statement
For Loop
One difference between a Hard Drive and RAM (random access memory) is
a Hard Drive is short term memory and is always available, even if the computer has been turned off
RAM is short term memory and is always available, even if the computer has been turned off
a Hard Drive is short term memory and is not available once the computer is turned off
RAM is short term memory and is not available once the computer is turned off
If this is your last question, get a paper from Mrs. Doulin and complete the last three questions of this review. If this is not you last question, finish the review and then get the last 3 questions.
Yes I read this and will answer the last 3 questions on paper
No I did not read this and I am taking a zero for the last 3 questions of the review
