@ -4,10 +4,11 @@ Measure the acceleration on the micro:bit in the "z" direction.
### ~avatar
```
Welcome! This activity will teach how to use the 1st micro:bit to chart the second micro:bit's acceleration in the "x" direction. 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. We will be able to get the acceleration value (g-force), in the specified "x" dimension. `Send number` will broadcast a number data packet to other micro:bits connected via radio.
