-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.

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.

-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.

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

+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.
