# 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()`.
