## Prior learning/place of lesson in scheme of work
|
|
|
|
Learn how to get the acceleration **acceleration**, `acceleration` value (g-force), in one of three specified dimensions. We will be learning how to get the acceleration using forever loop, a local variable, acceleration, the math library, as well as simple commands, such as led set brightness and led plot all.
