Construct a counter that uses acceleration.
To create a new script, go to the Create Code page and tap New Project under Block Editor.
Welcome! This activity will teach how to construct a pendulum that glows using acceleration. Let's get started!
Create a forever loop that will constantly display the appropriate brightness on the LED display. Now let's measure the acceleration on the y axis and store that value in a variable. The acceleration(y) function will provide the value.
Since the micro:bit will be swinging up and down, we need to store the variable called jumps. We will set the variable called jumps to 0 to store the number 0.
The function acceleration(y) gets the acceleration value (milli g-force), in the y dimension. If the acceleration(y)is greater than 2000 milli g-force, we will change jumps by 1.
If the acceleration(y)is greater than 2000 milli g-force, we will display the image with show LEDs to display a smiley face on the LEDs and clear screen to to turn off all the LED lights on the LED screen.
Now let's register an event handler that will execute whenever an input button (A) is pressed during program execution.
Let's show what the brightness of the micro:bit is by turning all the LEDs on!
