-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. 
+Connect the 2nd micro:bit to your computer using your USB cable. We should have two micro:bit devices attached to the computer.
