Show Number

Show a number on the LED screen. It will slide left if it has more than one digit.

basic.showNumber(2)

Parameters

• value is a Number.
• interval is an optional Number. It means the number of milliseconds before sliding the value left by one LED each time. Bigger intervals make the sliding slower.

Examples:

To show the number 10:

basic.showNumber(10)

To show the number stored in a variable:

let x = 1
basic.showNumber(x)

Example: count to 5

This example uses a for loop to show numbers 0 through 5 on the screen:

for (let i = 0; i < 6; i++) {
    basic.showNumber(i)
    basic.pause(200)
}

Other show functions

• Use show string to show a String with letters on the screen.
• Use show animation to show a group of pictures on the screen, one after another.
