Show Icon

Shows the selected icon on the LED screen

basic.showIcon(IconNames.Heart)

Parameters

• icon, the identifier of the icon to display
• interval (optional), the time to display in milliseconds. default is 600.

Example

This program shows a happy face and then a sad face with the show icon function, with a one second pause in between.

basic.showIcon(IconNames.Happy)
basic.pause(1000)
basic.showIcon(IconNames.Sad)

Beating Heart

You can create a beating heart by using the forever block as follows:

basic.forever(function () {
    basic.showIcon(IconNames.Heart)
    basic.showIcon(IconNames.SmallHeart)
})

Fast Beating Heart

You could slow down the previous animation by inserting a pause block:

basic.pause(1000)

…but how would you speed it up?

You can change the default pause value, which is set in the interval parameter, to be smaller than 600 by changing it in the JavaScript editor.

This JavaScript code creates a crazy fast heart beat! Did you know that a hamster’s heart beats at a rate this fast?

basic.forever(function () {
    basic.showIcon(IconNames.Heart, 60)
    basic.showIcon(IconNames.SmallHeart, 60)
})
