Ok, I created a fork of Ardublockly and a made a branch for my Arduboy Blocks:
GitHub aBlender/ardublocklyardublockly - Visual programming for Arduino. Based on blockly, implements Arduino code generation and facilitates program uploading.
Ardublockly is an easy to use, block-based programing environment for kids to use to program Arduino microcontrollers. It is based on an open source project from google called blockly, which allows developers to easily insert block programming tools into their projects. There are several benefits to using this type of development environment when teaching kids. First off it allows the kids to program in an intuitive way using blocks that fit together in a specific way to prevent errors. Also, one of the features of blockly is that it allows you to see the arduino code that is being written in real time. This allows kids to compare the block code that they write to the C code that is being sent to the arduino. The ardublockly project is run by gitHub user carlosperate and if you would like to try an example of ardublockly you can do so by clicking here.
In order to make Ardublockly easy to use for programming the blockly bot, some slight changes where made to the Ardublockly source code. First I had to add some new blocks to control the different functions of blockly bot like the motors and the ultrasonic sensors. To add the blocks for the ultrasonics I used the blockly block editor provided by Google to design the block itself and add the inputs it required. Once the block is designed it must be added to the toolbox on the left side of the Ardublockly interface by editing the toolbox XML file. Then a code generator must be created for that block. The code generator is a javascript file that tells ardublockly what Arduino code corresponds to this block and how the different inputs should change that code. Once this final step is complete the block appeared in the toolbox and functioned like any other block. Setting up the block for the robots motors was a bit different. Creating the code generator and the block itself was simple because blockly bot uses continuous rotation servo motors. This allowed me to simply duplicate the pre existing block for controlling servo motors and modify it for my purposes. One of the modifications I made was to add a trim function in the code generator. Because of the way the continuous rotation servo motors work, sometimes they move slowly when they are supposed to be stopped. This trim function allows you to change some numbers in an XML file to adjust the stopping point of the motors, fixing this issue.
