+
+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("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.
