+
+### ~
+
+## What you'll need: 
+
+* BBC micro:bit 
+* micro USB cable
+* Plate 
+* Tape 
+* Scissors
+
+![](/static/mb/lessons/seismograph11.png)
+
+# Engineering Steps
+
+## 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. Attach the micro:bit to the micro:bit USB cable.

+
+Computer Science: The seismograph has been built. We are ready to program the micro:bit to be a seismograph! 
+
+### ~
+
+# Programming Steps
+    
+## 3. 
+
+We will measure `acceleration (mg)` in terms of strength or Magnitude.
+
+```blocks
+input.acceleration(Dimension.Strength);
+```
+
+## 4. 
+
+Use the plot bar chart to visualize the acceleration on the LED screen. Use a forever to keep reading the acceleration value and displaying it on the screen.
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.Strength), 0);
+});
+
+```
+
+## 6. 
+
+At rest, the micro:bit is always subject to Earth gravity, whose magnitude is measured around ``1023``. Substract ``1023`` to measure a data close to ``0``. 
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
+});
+
+```
+

+
+Data Analysis: We now need to use the micro:bit to Analyze Data and chart for the strength of the acceleration.
+
+### ~
+
+# Data Analysis Steps
+
+## 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.

+
+## 8. 
+ 
+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. 
+
+![](/static/mb/lessons/seismograph22.png)
+
+## 9. 
+
+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.  
+

+
+## 10. 
+
+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)
+
+Third, notice that the LED display fluctates based on the movement of the micro:bit. 
+
+![](/static/mb/lessons/seismograph8.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.
+
+## 11. 
+
+In order to receive the the data plotted by Excel, click or tap anywhere in the on the chart data.
+
+![](/static/mb/analyze1.png)
+  
+## 12. 
+
+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/lessons/seismograph9.png)
+
+## 13. 
+
+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)
+
+## 14.
+
+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  
+
+
+## 15.
+
+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. 
+
+![](/static/mb/lessons/analyze16.png)
+
+Tip: If you don’t see the line chart, click the All Charts tab to see the line chart.
+
+## 16. 
+
+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.

+# Seismograph Challenge 
+
+Coding challenges for the seismograph. 
+
+
+### ~avatar avatar
+
+Engineering: In this project, you will build a remote control based on the seismograph micro:bit activity using a second micro:bit and micro USB cable. 
+
+### ~
+
+## What you'll need: 
+
+* BBC micro:bits (2)
+* micro USB cables (2) 
+* Plate 
+* Tape 
+* Scissors
+
+![](/static/mb/lessons/seis_challenge01.png)
+
+## Before we get started
+
+Complete the [seismograph](/lessons/seismograph/activity) activity and your code will look like this:
+
+```blocks
+basic.forever(() => {
+    led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
+});
+
+```
+
+### ~avatar avatar 
+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);
+});
+
+```
+
+## 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
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.Strength) - 1023);
+});
+
+```
+
+## 4. 
+We want to register code to run when a packet is received over radio. We can implement this code by adding `on data received`block found in the radio drawer.
+
+Your finished code will look like this:
+
+```blocks
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.Strength) - 1023);
+});
+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.
+
+Your finished code will look like this:
+
+```blocks
+basic.forever(() => {
+    radio.sendNumber(input.acceleration(Dimension.Strength) - 1023);
+});
+radio.onDataReceived(() => {
+    led.plotBarGraph(radio.receiveNumber(), 0);
+});
+```

+
+## 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.

+
+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.

+
+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.
+

+
+Tip: If you don’t see the line chart, click the All Charts tab to see the line chart.
+
+## 15.
