+
+Create a love meter with the micro:bit
+
+### ~avatar avatar
+
+### @video td/videos/love-meter-0
+
+Welcome! This activity will help you create a love meter with the micro:bit. Let's get started!
+
+To create a new script, go to the [Create Code](/microbit/create-code) page and tap *New Project* under *Block Editor*.
+
+### ~
+
+Begin by registering an event with `on pin pressed` *P0* to know when someone is holding pin *P0* and pin *Gnd*.
+
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    
+})
+
+```
+
+We are going to create a meter that displays a random number from *0* to *10*. We use *10* as `random number up to` returns a number between *0* and *n*.
+
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+})
+
+```
+
+Finally, let's show that number on the micro:bit. You are registering an event handler that will execute on the BBC micro:bit whenever the user holds the GND pin with one hand, and presses pin 0 with the other hand, thus completing a circuit
+
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+})
+
+```

+Excellent, you're ready to continue with the [challenges](/microbit/lessons/love-meter/challenges)

+# love meter blocks challenges
+
+Create a love meter with the micro:bit  
+
+## Before we get started
+
+You should work on these challenges after the following the [love meter activity](/microbit/lessons/love-meter/activity)
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+})
+
+```
+
+### Challenge 1
+
+Add a pause of 3000 milliseconds (3 seconds) after showing the number so that the number won't immediately disappear in the next challenge.
+
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+    basic.pause(3000)
+})
+```
+
+### Challenge 2
+
+If the rating **x** is between *0* and *3* (strictly less than *4*), display the text "HORRIBLE!".
+
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+    basic.pause(3000)
+    if (x < 4) {
+        basic.showString("HORRIBLE")
+    }
+})
+```
+
+### Challenge 3
+
+### @video td/videos/love-meter-3
+
+**If** the rating is between 4 and 7, display the text "MEDIOCRE!" **else** display the text "MATCHED!"
+
+```blocks
+input.onPinPressed(TouchPin.P0, () => {
+    let x = Math.random(10)
+    basic.showNumber(x)
+    basic.pause(3000)
+    if (x < 4) {
+        basic.showString("HORRIBLE")
+    } else if (x < 8) {
+        basic.showString("MEDIOCRE")
+    } else {
+        basic.showString("MATCHED")
+    }
+
+})
+```
+
+### Challenge 4
+
+Use `show LEDs` to display images instead of text for each case.

+# love meter blocks quiz answers
+
+The answers to the love meter quiz. 
+
+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. Write the code.
+
+Create a condition for `on pin pressed (P0)`.
+
+![](/static/mb/blocks/lessons/love-meter-0.jpg)
+
+## 3. What does this line of code doing?
+
+![](/static/mb/blocks/lessons/love-meter-6.png)
+
+<br/>
+
+It stores random number between 0 and 9 then stores that number in a variable.
+
+## 4. Why do you have to add 1 to variable x?
+
+![](/static/mb/blocks/lessons/love-meter-7.png)
+
+<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 micro:bit?
+
+<br/>
+
+You have told GND to complete the circuit.
