Arduino is a very popular hardware platform with makers & hobbyists. The microcontroller board provides sensors and actuators that allow for interaction with the physical world. The official website for Arduino (arduino.cc) defines it as:
Personally, I find Arduino to be a very versatile platform, that provides the opportunity for children to unleash their creativity. It would also allow for the development of interdisciplinary projects. While designing projects for children, I am always on the lookout for platforms that allow for the development of problem solving skills, logical analysis and thinking-outside-the-box, without getting trapped in the intricacies of the platform itself. I was thrilled by the opportunities that Arduino could provide, but was really skeptical about using its IDE for younger students.
Arduino is an open-source prototyping platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. All this is defined by a set of instructions programmed through the Arduino Software (IDE).A more detailed explanation of "What is Arduino?" can be found on the Arduino Intro page.

A program or code written for Arduino is called a "sketch". Arduino programs are usually written in C or C++. However, these languages are too complex for the younger kids to master and use. Hence, I did my bit of research and came across S4A - Scratch for Arduino. Developed by Citilab, a group in Spain, it is an improvised version of Scratch from MIT, with instructions that can be used to control the Arduino hardware. Here was the perfect solution to my dilemma: My students are already familiar with Scratch and absolutely love working with it; all they need to do is familiarize themseves with the extra set of instructions for the hardware. The instructions, written in plain English, are simple enough for the kids to understand and are very intuitive to use. It would open up the Arduino platform for them, without getting tangled in the intricacies of the syntax and grammar of a formal programming language.
The S4A site provides instructions on the download and installation; and frankly, it's quite a simple process. The main difference from the online Scratch is that you need to download and install S4A on your machine. And you are not allowed to share the S4A projects on the Scratch community website. The Arduino board is represented as a Sprite on this version of Scratch, and you have access to blocks that can perform digital/analog reads and writes, as well as blocks that can control motors. S4A is compatible with a few versions of Arduino, but I'll be primarily working with the Arduino Uno. Unless specifically mentioned, all references to Arduino in this blog will default to the Uno.
In the upcoming weeks, I'll be posting a few projects for Arduino, using S4A as the IDE.
