# Love Meter
|
|
|
|
## Introduction @unplugged
|
|
|
|
Make a love meter, how sweet! The @boardname@ is feeling the love, then sometimes not so much!
|
|
|
|
|
|
|
|
## 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.onPinTouched(TouchPin.P0, Button.Click, () => {
|
|
});
|
|
```
|
|
|
|
## 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.onPinTouched(TouchPin.P0, Button.Click, () => {
|
|
basic.showNumber(Math.randomRange(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.onPinTouched(TouchPin.P0, Button.Click, () => {
|
|
basic.showNumber(Math.randomRange(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.
