# Love Meter
## Introduction @unplugged
Make a love meter, how sweet! The @boardname@ is feeling the love, then sometimes not so much!
![Love meter banner message](/calliope/tutorials/05_love_meter_animation.gif)
## Step 1
Let's build a **LOVE METER** machine. Place an ``||input:on pin pressed||`` block to run code when pin **0** is pressed. Use ``P0`` from the list of pin inputs.
```blocks
input.onPinPressed(TouchPin.P0, () => {
});
```
## Step 2
Using ``||basic:show number||`` and ``||Math:pick random||`` blocks, show a random number from `0` to `100` when pin **0** is pressed.
```blocks
input.onPinPressed(TouchPin.P0, () => {
basic.showNumber(randint(0, 100));
});
```
## Step 3
Click on pin **0** in the simulator and see which number is chosen.
## Step 4
Show ``"LOVE METER"`` on the screen when the @boardname@ starts.
```blocks
basic.showString("LOVE METER");
input.onPinPressed(TouchPin.P0, () => {
basic.showNumber(randint(0, 100));
});
```
## Step 5
Click ``|Download|`` to transfer your code in your @boardname@. Hold the **GND** pin with one hand and press pin **0** with the other hand to trigger this code.
