+Notice that moving the micro:bit in the simulator from left to right (x direction) will change the values beneath the micro:bit in a range from 1023 to -1023 as measured in milli-gravities. By hovering over the micro:bit from left to right, you can observe the values change beneath the micro:bit simulator. The second observation will be that the LEDs  brightness on the 2nd micro:bit. There is a single LED turned on with the 1st micro:bit. Additionally, the graphs will reflect 0 acceleation for the 1st micro:bit. In this scenario, if you are adjusting the acceleration in the simualator, you are also changing your chart that will be produced.

+After running this simulatation several seconds by moving the micro:bit side to side in the x direction, you are ready to graph or chart the accceleration of the micro:bit.  We want a printout of our acceleration on Excel. We will graph the fluctuating acceleration of the simulation experiment.

+Welcome! The activity will teach you how to use the acceleration of the 1st micro:bit and return the acceleration value in a visual graphing display using 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. 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.
