The answers to the love meter quiz. #LED #screen #variables #docs
|
|
|
|
This is the answer key for the [love meter quiz](/microbit/lessons/love-meter/quiz).
|
|
|
|
## 1. What does on pin pressed ("P0") do?
|
|
|
|
<br/>
|
|
|
|
It's a method that runs code when the user holds the GND pin with a finger of one hand and presses pin P0, completing a circuit.
|
|
|
|
## 2. Create a condition for on pin pressed ("P1").
|
|
|
|
```
|
|
input.onPinPressed(TouchPin.P1, () => {
|
|
})
|
|
```
|
|
|
|
## 3. What does this line of code generate?
|
|
|
|
```
|
|
let x = Math.random(10)
|
|
```
|
|
|
|
<br/>
|
|
|
|
It generates a random number between 0 and 9 then stores that number in a variable.
|
|
|
|
## 4. Why do you have to add 1 to variable x?
|
|
|
|
```
|
|
x = x + 1
|
|
```
|
|
|
|
<br/>
|
|
|
|
You have to add 1 if you want to generate a random number between 1 and 10 .
|
|
|
|
## 5. Why do you have to hold ground (GND) to make this work on the BBC micro:bit?
|
|
|
|
<br/>
|
|
|
|
You have told GND to complete the circuit.
