Love meter

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 a ||input:on pin pressed|| block to run code when pin P0 is pressed.

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 P0 is pressed.

input.onPinPressed(TouchPin.P0, () => {
    basic.showNumber(Math.random(101));
});

Step 3

Show "LOVE METER" on the screen when the @boardname@ starts.

basic.showString("LOVE METER");
input.onPinPressed(TouchPin.P0, () => {
    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.
