# prank wifi quiz answers
|
|
|
|
create a fake wifi app to trick your friends.
|
|

|
|
## Directions
|
|
|
|
Use this activity document to guide your work in the [prank WiFi activity](/lessons/prank-wifi/activity)
|
|
|
|
Answer the questions while completing the tutorial. Pay attention to the dialogues!
|
|
|
|
## 1. Write the lines of code that takes the absolute value of the accelerations with respect to the x, y and z axis and stores the values as Local Variables
|
|
|
|
<br/>
|
|
|
|
```blocks
|
|
let xAccel = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel = Math.abs(input.acceleration(Dimension.Z))
|
|
```
|
|
|
|
<br/>
|
|
|
|
## 2. Write the lines of code that add all the accelerations together to get the total acceleration and stores the value as a Local Variable called "sum"
|
|
|
|
<br/>
|
|
|
|
<br/>
|
|
|
|
```blocks
|
|
let xAccel = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum = xAccel + yAccel + zAccel
|
|
```
|
|
|
|
<br/>
|
|
|
|
## 3. Write the 'If statement' used if the sum of the acceleration value is less than 1400 milli-gravitys. Then write the code that will plot an image of the fake amount of WiFi if the acceleration in this 'If statement'
|
|
|
|
<br/>
|
|
|
|
```blocks
|
|
let xAccel = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum = xAccel + yAccel + zAccel
|
|
if (sum < 1400) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. # # . .
|
|
# # # . .
|
|
`)
|
|
}
|
|
```
|
|
|
|
<br/>
|
|
|
|
## 4. Write tje 'If statement' used if the sum of the acceleration value is greater than 1400 milli-gravitys but less than 1680 milli-gravitys. Then write the code that will plot an image of the fake amount of WiFi inside this 'If statement'
|
|
|
|
<br/>
|
|
|
|
<br/>
|
|
|
|
```blocks
|
|
let xAccel = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum = xAccel + yAccel + zAccel
|
|
if (sum >= 1400 && sum < 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . # .
|
|
. . # # .
|
|
. # # # .
|
|
# # # # .
|
|
`)
|
|
}
|
|
```
|
|
|
|
## 5. Write the code to display this specific image on the device
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
<br/>
|
|
|
|
```blocks
|
|
let xAccel = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum = xAccel + yAccel + zAccel
|
|
if (sum >= 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
# . . . .
|
|
`)
|
|
}
|
|
```
