+
+Welcome! This tutorial will help you create a love meter with the BBC 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 **Touch Develop**.
+
+Begin by registering an event with `input->on pin pressed(PO)` to know when someone is holding pin ``P0`` and pin ``Gnd``.
+
+```
+input.onPinPressed("P0", () => {
+})
+```
+
+We are going to create a meter that displays a random number from 0 to 10. We use ``11`` as `math->random(n)` returns a number between ``0`` and ``n-1``.
+
+```
+input.onPinPressed("P0", () => {
+    let x = Math.random(11)
+})
+```
+
+Finally, let's show that number on the micro:bit.
+
+```
+input.onPinPressed("P0", () => {
+    let x_ = Math.random(11)
+    basic.showNumber(x_, 150)
+})
+```
