This lesson uses FTWCODE to create code and to connect to and navigate the Parrot Mambo Drone. FTWCODE can be accessed at: www.ftwcode.com 

Block-Based Coding - FTWCODE

Block-based programming in FTWCODE features a drag-and-drop capability. Blocks are snapped and stacked on top of each other to form actions. 

Blocks can be dragged and rearranged, and include common functions found in most programming languages.

Types of Blocks - FTWCODE

Closed Blocks:

The “Program Start” block and the “Functions” blocks are the only blocks that are considered Closed Blocks. Blocks can be placed inside of them but they cannot be placed inside of any other blocks.

Snap Blocks - FTWCODE

Snap blocks are any type of block that can be placed inside of a Closed Block. Snap Blocks often feature selectable elements. For example - the fly block lets you choose direction from a drop down, and enter time and power setting.

Building Code - FTWCODE

Blocks are only considered active when they are solid in color. “Program Start” is always active and will always be solid. Snap blocks will look "greyed out' when they are not active or inside of a closed block.

“Program Start” - FTWCODE

FTWCODE uses “Program Start” as the initial command (pictured below). To start programming, select the General category. This will expand the General category available block set. Then, drag the “Program Start” block onto the work area.

Programming in FTWCODE

After “Program Start”, each command needed is added in the order necessary to solve the problem and complete the code. 

Problem:

Program the drone to take off, hover, flip forward and then land. 

Solution:

Executing the Code

Once you have developed your code, you will need to connect to the drone and run the program.

Connecting to the Mambo - FTWCODE

Enable the computer’s Bluetooth function (desktop, laptop or Chromebook).  

Select Drone in the upper left-hand corner. 

Select Connect to bring up the pairing window. 

Select your individual drone which is identified by its unique six (6) digit serial number. (This number follows the prefix Mambo_.) 

Click on “Pair”. 

Drone will be connected and its current battery level will be displayed.

Run the Code

Once the drone is connected - you may hit the run the button to execute the code that you have programmed.
