+# Chart Acceleration: Challenge 
+
+### ~avatar avatar 
+
+Welcome! 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. 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.
+
+```blocks
+radio.sendNumber(input.acceleration(Dimension.X));
+```
+### ~
+We want to display the acceleration forever. In order to do so, we need a `forever` loop. A forever loop will repeat code in the background forever.
+
+```blocks
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.X));
+});
+
+
+```
+### ~
+We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`.
+
+```blocks
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.X))
+})
+radio.onDataReceived(() => {
+    
+})
+```
+### ~
+Finally, we want to chart the acceleration. So we must first implement `plot bar graph`. `Plot Bar Graph` will display a vertical bar graph based on the value and high value. In order to transfer the receive the number from the 1st micro:bit, we must implement `receive number` to constantly display a vertical bar graph based on the value. Remember, the value will equal to the micro:bit's acceleration in the "x" direction.
+
+```blocks
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.X))
+})
+radio.onDataReceived(() => {
+    led.plotBarGraph(radio.receiveNumber(), 1023)
+})
+
+```
+### ~
+Notice that moving the micro:bit the farthest direction in the x direction will be -1023 on the charting beneath the simulator. The second observation will be that the LEDs will be full 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.  
+
+![](/static/mb/acc.png)
+
+### ~
+NOTE: The colors of the charts reflect the color of the micro:bit simulator. In this instance, the micro:bits are blue and green. So the colors of the line graphs reflect the colors of the micro:bit
+ 
+ ### ~
+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.

+# Chart Acceleration: Activity 
+
+Measure the acceleration on the micro:bit in the "x" direction. 
+
+### ~avatar avatar
+
+Welcome! This activity will teach how to use the micro:bit to chart the acceleration in the "x" direction. Let's get started!
+
+
+### ~
+Let's measure `acceleration (mg)` in the "x" direction. Get the acceleration value (milli g-force), in one of three specified dimensions.
+
+
+```blocks
+input.acceleration(Dimension.X)
+
+```
+
+### ~
+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 the X dimension to measure the acceleration. 
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.X), 0)
+})
+
+```
+
+### ~
+Notice that moving the micro:bit in the simulator from left to right (x direction) changes 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 changing values beneath the micro:bit simulator. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the micro:bit simulator in the x direction. The line underneath the micro:bit simulator reflect the acceleration in the x direction. 
+
+NOTE: The colors of the charts reflect the color of the micro:bit simulator. In this instance, the micro:bit is yellow. So the color of the data line reflects the color of the micro:bit
+
+![](/static/mb/data4.png)
+
+### ~
+ 
+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. 
+
+### ~
+
+Review and write down your observations from the Excel data. Then chart or graph the data collected by using a tool in Excel. 
+
+The final part of this experiment is opening and reviewing the data in the Excel CSV file. Simply click on the line beneath the simulator. A CSV file will be generated to display the data points collected by moving the micro:bit in the X direction. Then click or tap on the data Excel file that was downloaded to your local Downloads Folder.
