Love Meter

Introduction

How much love 😍 are you emitting today? Create a 💓 LOVE METER 💓 machine with your micro:bit!

Step 1

Add an input ||input:on pin pressed|| function to run code when Pin P0 is pressed on the micro:bit. Type the code below, or drag a code snippet from the ||input:Input|| Toolbox category.

input.onPinPressed(TouchPin.P0, function() {
})

Step 2

Write some code to show a number in the ||input:on pin pressed|| function, using the basic ||basic:show number|| function.

input.onPinPressed(TouchPin.P0, function() {
    basic.showNumber(0)
})

Step 3

Instead of showing 0, use the ||math:randint|| function to show a random number between a minimum and maximum value.

input.onPinPressed(TouchPin.P0, function() {
    basic.showNumber(randint(0, 10))
})

Step 4

Everyone knows that love can be measured on a scale of 0 to 100. So, in the ||math:randint|| function, change the maximum value to 100.

input.onPinPressed(TouchPin.P0, function() {
    basic.showNumber(randint(0, 100))
})

Step 5

Now let’s be sure to label our Love Machine! Use the basic ||basic:show string|| function to show the message “LOVE METER” on the screen of the micro:bit.

basic.showString("LOVE METER")
input.onPinPressed(TouchPin.P0, function() {
    basic.showNumber(randint(0, 100));
})

Step 6

Let’s test our code. Press Pin 0 on the micro:bit on-screen simulator (bottom left). Numbers between 0-25 = 🖤 No Love, 26-50 = 🫶 BFF Love, 51-75 = 💘 Brokenhearted Love, 76-100 = 💖🔥 Fiery Hot Love!

Step 7

If you have a micro:bit device, connect it to your computer and click the |Download| button. Follow the instructions to transfer your code onto the micro:bit. Once your code has been downloaded, hold the GND pin with one hand and touch the 0 pin with the other hand. Your micro:bit 💓 LOVE METER 💓 machine will detect the love current flowing through your body!
