Lezione 8 mit appinventor

This introductory module will guide you through building a Magic 8-Ball app with App Inventor. When activated, your 8-ball will deliver one of its classic predictions, such as "It is decidedly so" or "Reply hazy, try again". The final Magic 8-Ball App will deliver a prediction from a list that you have designed. To get started, first we'll make a button with a picture on it, and program it to play a sound when the button is clicked.

You are going to tell your app how to behave when the Button is clicked. This is actually very simple in App Inventor, because the "code" for the program only consists of two blocks! Once the Blocks Editor is open, there are several options running along the left side of the screen. We refer to these as a "Palette with Drawers".

Under Screen1click on Button1. Drag the when Button1. Click block into the work area 1. Then, click on the Player1 drawer, drag the Player1. Play block into the work area and insert it into the when Button1.

Click block 2. They will click together like magnetic puzzle pieces. That's it! You've written the program for Part One of Magic 8-Ball. Now it's time to test that it's working right. You have now built an app! To test that it works, you either have to launch an emulator, or connect to a mobile device with the AI2 Companion.

Go back to the Setup Instructions if you do not have a device or an emulator running. Emulator : click on the picture, you will hear the sound play. Device : tap the picture, you will hear the sound play. Now that we've gotten the button to perform an action play a soundwe want to extend that action to include giving the user a prediction.

First we'll need two Labels: Label1 will display the instructions, and Label2 will display the chosen prediction. We'll use blocks to program a ListPicker to choose from a list of predictions. Each time the button is clicked, the app will change the text of Label2 to display the chosen prediction.Trying to push the limits!

In theory, it should be possible to write to any kind of device. However, make sure that the device uses the proper bit configuration:. What models exactly? With Arduino devices, it is compatible with any board. The only limitation that it presents is that you cannot load code from your smartphone to the Arduino board as that would require specifying the Arduino version.

Hello, It is a nice component. It works fine with bps but not with bps. It looks like baud rate is not being set with BaudRate property… just a guess…. Good to read that you connected the ESP with the Serial1 extension Can you post the blocks you used to connect, please?

I was testing the baud rate setting so it is set in Screen. Setting it in design view also works. Thanks for sending the aia file. On attaching the Arduino Uno, access to the app is requested see screenshotbut not when the ESP is attached. Thanks for the information. Hi, Doesnt work for me! Maybe it needs more than Android 4. So - some experiments later Taifun April 8,pm 2. Taifun Trying to push the limits! Diego April 8,pm 3.

However, make sure that the device uses the proper bit configuration: It is guaranteed that it will work with Arduino devices.This introductory module will guide you through building a Magic 8-Ball app with App Inventor.

The final Magic 8-Ball App will deliver a prediction from a list that you have designed. To get started, first we'll make a button with a picture on it, and program it to play a sound when the button is clicked.

In the upper right corner of the Designer, click on the Blocks Editor button. Wait for a few moments while the blocks editor loads. This takes some time, and often requires you to click accept, ok, or keep as the java program downloads to your computer. Be sure to look at the very top or very bottom of your browser to see if it is prompting you to accept.

If you are having trouble loading the Blocks Editor, go back to the Setup Instructions for help. Now you are going to tell your app how to behave when the button is clicked. This is actually very simple in App Inventor, because the "code" for the program only consists of two blocks!

Once the Blocks Editor is open, there are several options running along the left side of the screen. We refer to these as "Palettes" with Drawers. From the My Blocks palette, click on the Button1 drawer.

Drag the when Button1. Click block into the work area 1. From the My Blocks palette, click on the Sound1 drawer, drag the Sound1. Play block into the work area and insert it into the when Button1. Click block 2. They will click together like magnetic puzzle pieces. That's it! You've written the program for Part One of Magic 8-Ball. Now it's time to test that it's working right. You have now built an app! To test that it works, you either have to launch an emulator, or connect to a phone.

Go back to the Setup Instructions if you do not have a phone or an emulator running. Emulator : click on the picture, you will hear the sound play.

Phone : tap the picture, you will hear the sound play. Now that we've gotten the button to perform an action play a soundwe want to extend that action to include giving the user a prediction. First we'll need two labels: Label1 will display the instructions, and Label2 will display the chosen prediction.Dictionaries, called in other languages terms such as maps, associative arrays or lists, are data structures that associate one value, often called the key, with another value.

The above example shows that in JSON the keys quoted text before the : can map to different types of values. The allowed types are number, text, other dictionaries, booleans, and lists. In the blocks language, you can bulid this dictionary as follows:. The create empty dictionary block creates a dictionary without any key-value pairs. Entries can be added to the empty dictionary using the set value for key block. The create empty dictionary block can also be turned into a make a dictionary block by using the blue mutator button to add pair entries.

The make a dictionary is used to create a dictionary with a set of pair s known in advance. Additional entries can be added using set value for key. The pair block is a special purpose block used for constructing dictionaries. The get value for key block checks to see if the dictionary contains a corresponding value for the given key.

If it does, the value is returned. Otherwise, the value of the not found parameter is returned. This behavior is similar to the behavior of the lookup in pairs block. The set value for key block sets the corresponding value for the given key in the dictionary to value.

If no mapping exists for keya new one will be created. Otherwise, the existing value is replaced by the new value. The delete entry for key block removes the key-value mapping in the dictionary for the given key.

If no entry for the key exists in the dictionary, the dictionary is not modified. The get value at key path block is a more advanced version of the get value for key block.

Rather than getting the value of a specific key, it instead takes a list of valid keys and numbers representing a path through a data structure. The get value for key block is equivalent to using this block with a key path of length 1 containing the key. For example, the following two blocks would return "Tim the Beaver" :. It walks the data structure, starting from the initial dictionary, using the path provided in order to retrieve values nested deeply in complex data structures.We are still developing the program based on submissions for the different calls.

Check back periodically for updates. Breakfast and lunch will be provided for all three days of the conference. Coffee breaks will be offered between the two morning sessions and two afternoon sessions of each day.
