The activity will teach you how to use the acceleration of the 1st micro:bit and to visualize the acceleration on the 2nd micro:bit. Let's get started! - -### ~ -Let's measure `acceleration (mg)` and then `send number`. `Acceleration` is measured in **milli-gravities**, so a value of -1000 is equivalent to -1g or -9.81m/s^2.
