Welcome! This tutorial will help you display an arrow pointing toward the logo! Let's get started.
~
Using the accelerometer sensor, the BBC micro:bit can detect when the logo is oriented up. We call that the logo up event. We will use input->on logo up to register an event handler that will run when the logo up event happens.
input.onLogoUp(() => {
}) // ***
When the BBC micro:bit goes logo up, the code nested under the basic->on logo up function will run. Let's add a line of code to plot an image in there.
input.onLogoUp(() => {
basic.showLeds(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`, 400) // ***
})
Run your code and try to turn around the BBC micro:bit to see the logo up event in action!
