# love meter
## ~avatar avatar
Use pins and your body to change the display!
## ~
## Step 1
Use [on pin pressed](/reference/input/on-pin-pressed) to show a random number
when pin P0 is pressed (hold the GND pin with other hand):
Let's build a **LOVE METER** machine. Place a ``||input:on pin pressed||`` block to run code
when pin ``P0`` is pressed.
```blocks
input.onPinPressed(TouchPin.P0, () => {
basic.showNumber(Math.random(11));
});
```
## Step 2
Show a string when pin P1 is pressed:
Using ``||basic:show number||`` and ``||Math:pick random||`` blocks,
show a random number from 0 to 100 when pin ``P0`` is pressed.
```blocks
input.onPinPressed(TouchPin.P0, () => {
basic.showNumber(Math.random(11));
});
input.onPinPressed(TouchPin.P1, () => {
basic.showString("LOVE?");
basic.showNumber(Math.random(101));
});
```
## Step 3
Show a heart when pin P2 is pressed:
Show ``"LOVE METER"`` on the screen when the @boardname@ starts.
```blocks
basic.showString("LOVE METER");
input.onPinPressed(TouchPin.P0, () => {
basic.showNumber(Math.random(11));
});
input.onPinPressed(TouchPin.P1, () => {
basic.showString("LOVE?");
});
input.onPinPressed(TouchPin.P2, () => {
basic.showLeds(`
. # # # .
# # # # #
# # # # #
. # # # .
. . # . .
`);
basic.showNumber(Math.random(101));
});
```
## Step 4
Click ``|Download|`` to transfer your code in your @boardname@. Hold the ``GND`` pin with other hand and press pin ``P0`` with the other hand to trigger this code.
