# prank wifi challenges
|
|
|
|
create a fake wifi app to trick your friends.
|
|
|
|
## Before we get started
|
|
|
|
Complete the following exercise. Your code should look like this:
|
|
|
|
```blocks
|
|
basic.showString("Check Wifi", 150)
|
|
basic.forever(() => {
|
|
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(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. # # . .
|
|
# # # . .
|
|
`)
|
|
} else if (sum >= 1400 && sum < 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . # .
|
|
. . # # .
|
|
. # # # .
|
|
# # # # .
|
|
`)
|
|
} else if (sum >= 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
# . . . .
|
|
`)
|
|
}
|
|
})
|
|
|
|
```
|
|
|
|
## Challenge 1
|
|
|
|
What if wanted to show the maximum connectivity of wifi instead of just 1, 3, or 4 bars?
|
|
|
|
Let's start by changing the first **IF** statement to `if sum <1200`.
|
|
|
|
Edit this line: if sum is greater than 1400 then just click on the `1400` and backspace until you can add your own number of `1200`.
|
|
|
|
```blocks
|
|
basic.showString("Check Wifi", 150)
|
|
basic.forever(() => {
|
|
let xAccel1 = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel1 = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel1 = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum1 = xAccel1 + yAccel1 + zAccel1
|
|
if (sum1 < 1200) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. # # . .
|
|
# # # . .
|
|
`)
|
|
} else if (sum1 >= 1400 && sum1 < 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . # .
|
|
. . # # .
|
|
. # # # .
|
|
# # # # .
|
|
`)
|
|
}
|
|
else if (sum1 >= 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
# . . . .
|
|
`)
|
|
}
|
|
})
|
|
```
|
|
|
|
## Challenge 2
|
|
|
|
Let's add an **IF** at the bottom of your code that checks to see if `sum >= to 1200` **and** if `sum <1400`
|
|
|
|
```blocks
|
|
basic.showString("Check Wifi", 150)
|
|
basic.forever(() => {
|
|
let xAccel2 = Math.abs(input.acceleration(Dimension.X))
|
|
let yAccel2 = Math.abs(input.acceleration(Dimension.Y))
|
|
let zAccel2 = Math.abs(input.acceleration(Dimension.Z))
|
|
let sum2 = xAccel2 + yAccel2 + zAccel2
|
|
if (sum2 < 1200) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . # . .
|
|
. # # . .
|
|
# # # . .
|
|
`)
|
|
} else if (sum2 >= 1400 && sum2 < 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . # .
|
|
. . # # .
|
|
. # # # .
|
|
# # # # .
|
|
`)
|
|
}
|
|
else if (sum2 >= 1680) {
|
|
basic.showLeds(`
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
. . . . .
|
|
# . . . .
|
|
`)
|
|
}
|
|
if (sum2 >= 1200 && sum2 < 1400) {
|
|
basic.showLeds(`
|
|
. . . . #
|
|
. . . # #
|
|
. . # # #
|
|
. # # # #
|
|
# # # # #
|
|
`)
|
|
}
|
|
})
|
|
```
|
|
|
|
## Challenge 3
|
|
|
|
Now it's your turn! Be creative and change the Wifi meter images to your own wifi image you're sure will prank your friends by editing the lines that call `showLeds()`.
