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.

# Science Steps
|
||||||
|
|
||||||
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.
|
## 7.
|
||||||
|
|
||||||
|
First, notice that moving the micro:bit in the simulator in any direction, you will change the acceleration value, which is being displayed as the same color as the micro:bit simulator. Also, notice that by moving the micro:bit simulator, there is a changing acceleration value. Second, the flat colored horizontal line will start a waving line to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the micro:bit simulator.

||||||
|
|
||||||

Connect a micro:bit to your computer using your USB cable
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seismograph33.png)
|
||||||
|
|
||||||
|
Click or tap the compile button for the seismograph program to run the program on the micro:bit.

|
||||||
|
|
||||||
|
A black line should appear directly beneath the colored line. The black line measures the micro:bit acceleration. And the colored line measures micro:bit simulator acceleration.
|
||||||
|
|
||||||
|
Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).
|
||||||
|
|
||||||
|
Every time the micro:bit moves in any direction, you generate data points that can be reviewed in Excel later. The more attempts to move the micro:bit, the more data to be reviewed in Excel.

Please find seismogrph experiment obervations:
|
||||||
|
|
||||||
|
First, notice that moving the micro:bit in any direction, you will change the acceleration value, which is being displayed as a milli-gravities value. By moving the micro:bit, there will be a changing acceleration value.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seismograph7.png)
|
||||||
|
|
||||||
|
Second, the horizontal line will move to plot the value of the strength as measured in milli-gravities. The horizontal line's movement is based on the micro:bit acceleration in Magnitude or Strength.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seismograph6.png)
|

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.

## Before we get started
|
||||||
|
|
||||||
|
Complete the [seismograph](/lessons/seismograph/activity) activity and your code will look like this:
|
||||||
|
|
||||||
```blocks
|
```blocks
|
||||||
basic.forever(() => {
|
basic.forever(() => {
|
||||||
radio.sendNumber(input.acceleration(Dimension.X));
|
led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
|
||||||
});
|
});
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||

Computer Science: Welcome! The activity will teach you how to code the acceleration of the 1st micro:bit and to visualize the acceleration on the 2nd micro:bit. Let's get started!

# Computer Science Steps
|
||||||
|
|
||||||
|
## 1.
|
||||||
|
We want to simply detach the blocks from the recent activity. We will use blocks from the activity to create a brand new program to show the way micro:bit devices communicate through the BLE (Bluetooth low energy) radio.
|
||||||
|
|
||||||
|
```shuffle
|
||||||
|
basic.forever(() => {
|
||||||
|
led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
|
||||||
|
});
|
||||||
|
|
||||||
```
|
```
|
||||||
### ~
|
|
||||||
We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`.
|
## 2.
|
||||||
|
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.
|
||||||
|
|
||||||
|
We need add send number block found in the Radio drawer. We will attach send number to acceleration and subtract the gravity from acceleration strength.
|
||||||
|
|
||||||
|
Your finished code will look like this:
|
||||||
|
|
||||||
|
```blocks
|
||||||
|
radio.sendNumber(input.acceleration(Dimension.Strength) - 1023);
|
||||||
|
```
|
||||||
|
|
||||||
|
## 3.
|
||||||
|
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. We need attach forever loop to send number.
|
||||||
|
|
||||||
|
Your finished code will look like this:
|
||||||
|
|
||||||
```blocks
|
```blocks
|
||||||
basic.forever(() => {
|
basic.forever(() => {
|
||||||
radio.sendNumber(input.acceleration(Dimension.X))
|
radio.sendNumber(input.acceleration(Dimension.Strength) - 1023);
|
||||||
})
|
});
|
||||||
radio.onDataReceived(() => {
|
|
||||||
|
|
||||||
})
|
|
||||||
```
|
```
|
||||||

||||||

|
});
|
||||||
|
radio.onDataReceived(() => {
|
||||||
|
});
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5.
|
||||||
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.

|
led.plotBarGraph(radio.receiveNumber(), 0);
|
||||||
})
|
});
|
||||||
|
|
||||||
```
|
```
|
||||||
### ~
|
|
||||||
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.

# Science Steps
|
||||||
|
|
||||||
|
## 6.
|
||||||
|
First, notice that moving the 1st micro:bit in the simulator in any direction, you will change the acceleration value of the 2nd micro:bit. Also, notice that by moving the micro:bit simulator, there is a changing acceleration value of the second micro:bit. Second, the flat colored horizontal line will start a waving line on the 2nd micro:bit to display the value of the strength as measured in milli-gravities. Finally, notice that the LED display will fluctate based on the movement of the 2nd micro:bit simulator.
|
||||||
|
|
||||||
|
![](/static/mb//lessons/seis_challenge02.png)
|
||||||
|
|
||||||
|
## 7.
|
||||||
|
|
||||||
|
Connect the 2nd micro:bit to your computer using your USB cable. We should have two micro:bit devices attached to the computer.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seismograph33.png)
|
||||||
|
|
||||||
|
## 8.
|
||||||
|
|
||||||
|
Click or tap the compile button for the seismograph program to run the program on the 1st micro:bit and 2nd micro:bit.
|
||||||
|
|
||||||
|
## 9.
|
||||||
|
|
||||||
|
The black lines should appear directly beneath the colored lines. The black lines measure the micro:bit acceleration. And the colored lines measures micro:bit simulator acceleration.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seis_challenge05.png)
|
||||||
|
|
||||||
|
Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seis_challenge06.png)
|
||||||
|
|
||||||
|
Every time the micro:bit moves in any direction, you generate data points that can be reviewed in Excel later. The more attempts to move the micro:bit, the more data to be reviewed in Excel. Notice that the LED on the 2nd micro:bit changes to communicate the movement of the 1st micro:bit.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seis_challenge04.png)
|
||||||
|
|
||||||
|
Now we are ready to graph or chart the accceleration of the micro:bit. We want a printout of the micro:bit acceleration graphed in Excel.
|
||||||
|
|
||||||
|
## 10.
|
||||||
|
|
||||||
|
In order to receive the the data plotted by Excel, click or tap anywhere in the on the chart data.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/seis_challenge07.png)
|
||||||
|
|
||||||
|
## 11.
|
||||||
|
|
||||||
|
You have two options to Analyze Data:
|
||||||
|
|
||||||
|
* Local File: Save the data to your local Downloads folder and open it in Excel.
|
||||||
|
* Stream to Cloud: Upload your data to Microsoft Azure to analyze it.
|
||||||
|
|
||||||
|
Click or tap Download data
|
||||||
|
|
||||||
|
![](/static/mb/seismograph9.png)
|
||||||
|
|
||||||
|
## 12.
|
||||||
|
|
||||||
|
A CSV file will be generated to display the data points collected by the micro:bit. Click or tap on the data Excel file that was downloaded to your local Downloads Folder.
|
||||||
|
|
||||||
|
![](/static/mb/lessons/analyze9.png)
|
||||||
|
|
||||||
|
## 13.
|
||||||
|
|
||||||
|
Select the data that you want to include in your chart. The chart should include the first two columns: time and acceleration.
|
||||||
|
|
||||||
|
Click or tap on the first two columns (A, B) to include time and acceleration data from the micro:bit. We only need the first two columns (A, B) because the 2nd micro:bit changes have been communicated by the 1st micro:bit. So the data points of the seismograph are being recorded on the 1st micro:bit.
|
||||||
|
|
||||||
|
## 14.
|
||||||
|
|
||||||
|
Click or tap on Insert then select Recommended Charts. We can select a chart that’s just right for the data.
|
||||||
|
|
||||||
|
![](/static/mb/analyze3.png)
|
||||||
|
|
||||||
|
On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data.
|
||||||
|
|
||||||
|
We want to select the chart called Line. A line chart is used to display trends over time. We will use the line chart because there are many data points over time.
|
||||||
|
|
||||||
|
Click on the chart type to see how your data will look in that format. When you find the chart type that you want, click it, and then click OK.
|
||||||
|

|
|
||||||
|
Tip: If you don’t see the line chart, click the All Charts tab to see the line chart.
|
||||||
|
|
||||||
|
## 15.
|
||||||
|
|
||||||
|
Use the Chart Elements, Chart Styles, and Chart Filters buttons next to the upper-right corner of the chart to add chart elements like axis titles or data labels, to customize the look of your chart
|
||||||
|
|
||||||
|
Alternatively, click or tap on the Design Ribbon.
|
||||||
|
|
||||||
|
Let's select Style 10 as an example.
