1. Prepare Tape: Measure and cut approximately 10mm of tape. The tape will be fastened to a micro USB cable.
2. Fasten Tape: Fasten tape to the micro USB cable and to the plate.

Use the plot bar chart to visualize the acceleration on the LED screen of the micro:bit in the specified range. You implement plot Bar Graph to display a vertical bar graph based on the "value" and "high" value. Then you must insert acceleration in based on strength.

Notice that making vibrating the object below the micro:bit changes the values and the line appears as a wave to display the value of the strength as measured in milli-gravities. By making the object below the micro:bit vibrate, you will observe changing values of the micro:bit. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the micro:bit strength.

Vigorously move the micro:bit in the micro:bit simulatator by moving the micro:bit image from side to side. Every time the micro:bit moves in the x direction in the simulator, you are generating data points that can be reviewed in Excel. The more attempts to move the micro:bit from side to side, the more data being saved in Excel. After you have vigarously moved the micro:bit simulator from side to side for a sufficient amount of time, you are ready to graph or chart the accceleration of the micro:bit. We want a printout of our acceleration on Excel that can be graphed in Excel.
