# zoomer blocks lesson measure the acceleration on the micro:bit in the "z" direction #acceleration #var #docs #if #show ### @video td/videos/zoomer-0 ## Topic Acceleration ## Quick Links * [activity](/microbit/lessons/zoomer/activity) * [challenges](/microbit/lessons/zoomer/challenges) ## Prior learning/place of lesson in scheme of work Learn how to get the **acceleration**, `acceleration` in one of three specified dimensions. We will be learning how to get the acceleration using a forever loop, local variables, input on button pressed, as well as simple commands, such as show number and pause. ## Documentation ```docs basic.forever(() => { }) let x = 0 input.acceleration(Dimension.X) if (true) { } input.buttonIsPressed(Button.A) basic.showNumber(0) ``` ## Objectives * learn how to repeat code in the background forever * learn how to create a variable to store data * learn how to get the acceleration value (g-force), in one of three specified dimensions * learn how to pause your code for the specified number of milliseconds * learn how to conditionally run code depending on whether a condition is true or not * learn how to get the state of an input button * learn how to show a number on the LED screen
