## Name
## Directions
Use this activity document to guide your work in the [glowing pendulum activity](/lessons/charting/acceleration)
Answer the questions while completing the tutorial. Pay attention to the dialogues!
## 1. Why are you creating a 'forever' loop?
<br/>
We are creating a forever loop to constantly display the appropriate brightness on the LED display.
## 2. Write the line of code to measure the acceleration with respect to the "x" axis and display this value in a bar graph.
<br/>
```blocks
led.plotBarGraph(input.acceleration(Dimension.X), 0)
```
## 3. After vigarously moving the micro:bit from side to side along the "x" axis for a sufficient amount of time,insert the Excel graph for displaying a line chart used to display trends over time.

# Seismograph Lesson
Build a seismograph with household materials
## Topic
Acceleration & Analog Read Pin
## Quick Links
* [activity](/lessons/seismograph/activity)
* [challenge](/lessons/seismograph/challenges)
## Prior learning/place of lesson in scheme of work
Learn how to **show LEDs** to turn on a LED light pattern on the LED screen. We will be learning basic comments such as show LEDs and pause.
## Documentation
```cards
basic.forever(() => {
});
led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
led.plotBarGraph(pins.analogReadPin(AnalogPin.P0), 0);
```
## Objectives
* learn how to repeat code forever in the background
* learn how to display a vertical bar graph based on the value.
* learn how to return the sum of the two numbers
* learn how to get acceleration value in milli-gravitys
* learn how to read the connector value as analog as a value comprised between 0 and 1023

# Seismograph Activity
### ~avatar avatar
In this project, you will build your own seismograph.
## What you'll need:
* micro:bit
* USB cable
* Scissors
* Glue gun
* String
* Cup (Plastic or Paper)
* Magnet
Welcome! This activity will teach how to use the micro:bit to chart the strength of the acceleration. Let's get started!
1. Setup Cup: Use scissors to cut a usable window on the cup, which will be a square sized hole at the lid side of the cup. Use scissors to create a small hole in the center of the base of the cup.
2. Fasten Magnet: Fasten end of the string to the magnet with glue
3. Secure String: Fasten string to base of the cup and hang the remaining string outside the base of the cup.
### ~avatar avatar
Seismograph built, let's code!
### ~
4. Go to Codemicrobit.com
Click or tap Create Code
Click or tap Block Editor
### ~
5.
We will measure `acceleration (mg)` in terms of strength. Get the acceleration value (milli g-force), as measured in strength.
```blocks
input.acceleration(Dimension.Strength);
```
### ~
6.
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.
```blocks
basic.forever(() => {
led.plotBarGraph(input.acceleration(Dimension.Strength), 0);
});
```
### ~
7.
Finally, we subtract the gravity from acceleration strength.
```blocks
basic.forever(() => {
led.plotBarGraph(input.acceleration(Dimension.Strength) - 1023, 0);
});
```
### ~
8.
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.
NOTE: The black color reflects the micro:bit device.

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.

Click any 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. 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.

# charting light
Measure the light level on the micro:bit from light to dark.
### ~avatar avatar
Welcome! This activity will teach how to use the micro:bit to chart the light level from light to dark. Let's get started!
### ~
Let's measure the light level from dark to light. Get the acceleration value (milli g-force), in one of three specified dimensions.
```blocks
input.lightLevel()
```
### ~
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
