Welcome! This activity will help you create a love meter with the micro:bit. Let's get started!
To create a new script, go to the Create Code page and tap New Project under Block Editor.
~
Begin by registering an event with on pin pressed P0 to know when someone is holding pin P0 and pin Gnd.
input.onPinPressed(TouchPin.P0, () => {
})
We are going to create a meter that displays a random number from 0 to 10. We use 10 as random number up to returns a number between 0 and n.
input.onPinPressed(TouchPin.P0, () => {
let x = Math.random(10)
})
Finally, let's show that number on the micro:bit. You are registering an event handler that will execute on the BBC micro:bit whenever the user holds the GND pin with one hand, and presses pin 0 with the other hand, thus completing a circuit
input.onPinPressed(TouchPin.P0, () => {
let x = Math.random(10)
basic.showNumber(x)
})
