### @description code to make the Milky Monster alive
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Add code to make the Milky Monster move.
|
||||
|
||||
### ~
|
||||
|
||||
## Duration: ~30 minutes
|
||||
|
||||
## Step 1: calibrate servo
|
||||
|
||||
In order for the Milky Monster to move, the @boardname@ needs to command the servo to go between ``0`` and ``180`` degrees at a certain pace. In the code below:
|
||||
- the user pressed button ``A`` to switch the servo to 180 degrees (to close the mouth of Milky Monster).
|
||||
- the user pressed button ``B`` to switch the servo to 0 degrees (to open the mouth of Milky Monster).
|
||||
|
||||
```blocks
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
pins.servoWritePin(AnalogPin.P0, 180)
|
||||
basic.showNumber(180)
|
||||
})
|
||||
input.onButtonPressed(Button.B, () => {
|
||||
pins.servoWritePin(AnalogPin.P0, 0)
|
||||
basic.showNumber(0)
|
||||
})
|
||||
basic.showString("calibrate")
|
||||
|
||||
```
|
||||
|
||||
## Step 2: attach rotor
|
||||
|
||||
The servo should be positioned on 180 degrees **before** attaching the rotor to it. This is to make sure the mouth of the Milky Monster will be closed once the servo reaches 180 degrees.
|
||||
|
||||
### ~ hint
|
||||
|
||||
You may use a philips scew driver to attach the rotor to the servo.
|
||||

|
||||
|
||||
## Step 3: check calibration
|
||||
|
||||
When the user pressed ``A`` the servo rotor should be in 'up' position.
|
||||
|
||||
https://youtu.be/bAqXEawUsSM
|
||||
|
||||
## Step 4: connect cord to rotor
|
||||
|
||||
Connect the cord to the servo rotor while mouth of Milky Monster is **closed**.
|
||||
|
||||
https://youtu.be/AWsnwk_iA_A
|
||||
|
||||
## Step 5: connect cables to @boardname@
|
||||
|
||||
Connect cables from @boardname@ to the servo and place the battery.
|
||||
|
||||
https://youtu.be/fAR58GJUZdM
|
||||
|
||||
## Step 6: code light sensor
|
||||
|
||||
Code the lightsensor on the @boardname@ to control the servo.
|
||||
|
||||
```blocks
|
||||
basic.forever(() => {
|
||||
pins.servoWritePin(AnalogPin.P0, input.lightLevel())
|
||||
led.plotBarGraph(
|
||||
input.lightLevel(),
|
||||
0
|
||||
)
|
||||
})
|
||||
```
|
||||
|
||||
## Step 6: Ready!
|
||||
|
||||
Your Milky Monster is ready!

Remote control your Milky Monster with another @boardname@
|
||||
|
||||
### ~
|
||||
|
||||
## Duration: ~30 minutes
|
||||
|
||||
You will need 2 @boardname@ for this part. By using the radio, we can make the Milky Monster controlled by another @boardname@.
|
||||
Download the code below to the @boardname@ on the Milky Monster and another "controller" @boardname@. Whenere A is pressed, the Milky Monster will move once.
|
||||
|
||||
```blocks
|
||||
radio.onDataPacketReceived(({receivedNumber}) => {
|
||||
pins.servoWritePin(AnalogPin.P0, 0)
|
||||
basic.pause(500)
|
||||
pins.servoWritePin(AnalogPin.P0, 180)
|
||||
basic.pause(500)
|
||||
})
|
||||
input.onButtonPressed(Button.A, () => {
|
||||
radio.sendNumber(0)
|
||||
})
|

```
|

|
||||
|
||||
## Step 3: cut carton
|
||||
|
||||

https://youtu.be/pvC3Tnhe5QU
|
||||
|
||||
## Step 4: create mouth
|
||||
|
||||
Cut the cardboard halfways and fold the corners. This will be the mouth of the Milky Monster.
|

|
||||
https://youtu.be/Yyk1zW4sFoM
|
||||
|

|
||||
|
||||
## Step 6: connect cord
|
||||
|
||||
Using scissors, create a small whole to insert the cord. Tape the cord on the backsite of the mouth.
|
||||
|
||||
|
||||
|
||||
Once finished position the mouth in upward position and fix the cord between the cap.

|
||||
|
||||
## Step 7: create space for @boardname@
|
||||
|
||||
Use scissors to create space at the bottom of the Milky Monster to attach the @boardname@.
|
||||
|
||||
https://youtu.be/3FUNI0GSbNc

|
||||
If you don't have the 3D-printed clips available, [download on thingiverse](http://www.thingiverse.com/thing:2185971) , or fix the servo using tyraps or a glue gun.

Measure the acceleration on the @boardname@ in the "x" direction.
|
||||
|
||||
### ~avatar avatar
|
||||
|
||||
Welcome! This activity will teach how to use the @boardname@ 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 @boardname@ 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 @boardname@ in the simulator from left to right (x direction) changes the values beneath the @boardname@ in a range from 1023 to -1023 as measured in milli-gravities. By hovering over the @boardname@ from left to right, you can observe changing values beneath the @boardname@ simulator. Also, the LEDs shown on the Bar Graph fluctates based on the movement of the @boardname@ simulator in the x direction. The line underneath the @boardname@ simulator reflect the acceleration in the x direction.
|
||||
|
||||
NOTE: The colors of the charts reflect the color of the @boardname@ simulator. In this instance, the @boardname@ is yellow. So the color of the data line reflects the color of the @boardname@
|
||||
|
||||
|
||||
|
||||
### ~
|
||||
|
||||
Vigorously move the @boardname@ in the @boardname@ simulatator by moving the @boardname@ image from side to side. Every time the @boardname@ 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 @boardname@ from side to side, the more data being saved in Excel. After you have vigarously moved the @boardname@ simulator from side to side for a sufficient amount of time, you are ready to graph or chart the accceleration of the @boardname@. We want a printout of our acceleration on Excel that can be graphed in Excel.
|
||||
|
||||
### ~
|
||||
|
||||
We want to chart 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 @boardname@ in the X direction. Then click or tap on the data Excel file that was downloaded to your local ``Downloads`` Folder.
|
||||
|
||||
|
||||
### ~
|
||||
|
||||
|
||||
First, click or tap on the first two columns (A, B) to include the time of the data being collected; b) the results of acceleration data on the @boardname@
|
||||
|
||||
|
||||
|
||||
Use the Recommended Charts command on the Insert tab to quickly create a chart that’s just right for your data.
|
||||
|
||||
* Select the data that you want to include in your chart.
|
||||
|
||||
* Click Insert > Recommended Charts.
|
||||
|
||||
|
||||
|
||||
* On the Recommended Charts tab, scroll through the list of chart types that Excel recommends for your data. Pick the **scatter plot**.
