Introduction

After helping many people get started with the world of Arduino and electronics,  we still find a small percentage of people who are turned off by the concept of programming or have trouble breaking larger tasks into smaller ones with regards to writing algorithms for their code/sketch.

So after being introduced to a new graphical programming tool called “Ardublock“, we were excited about the possibilities wanted to share it with our readers. Ardublock provides a truly graphical and non-coding solution to controlling an Arduino, that is an open-source product and thus free to download and try for yourself.

Installation

Ardublock is a Java application that runs from inside the Arduino IDE, which can be downloaded from here. It’s only one file, that needs to be placed in a new folder in the Arduino IDE. The folder names must be the same as shown below:

Once you’ve copied the file, simply open the Arduino IDE and select Ardublock from the Tools menu:

From which point a new window appears – the Ardublock “development environment”:

 Using Ardublock

It’s quite simple – you simply select the required function from the menu on the left and drag it into the large area on the right. For a quick example where we blink the onboard LED on and off – watch the following video:

The following image is the screen capture of the program from the video:

As you can see the “blocks” just fit together, and parameters can be changed with the right mouse button. After a few moments experimenting with the Ardublock software you will have the hang of it in no time at all.

And thus you can demonstrate it to other people and show them how easy it is. And there is much more than just digital output controls, all the functions you’re used to including I2C, variables, constants, servos, tone and more are available.

The only technical thing you need to demonstrate is that the Arduino IDE needs to stay open in the background – as once you have finished creating your program, Ardublock creates the required real Arduino sketch back in the IDE and uploads it to the board.

This is also a neat function – the user can then compare their Ardublock program against the actual sketch, and hopefully after a short duration the user will have the confidence to move on with normal coding.

Conclusion

Ardublock provides a very simple method of controlling an Arduino, and makes a great starting point for teaching the coding-averse, very young people or the cognitively-challenged. It’s open source, integrates well with the official IDE and works as described – so give it a go.
