Scratch For Arduino could be explained as a child-friendly version of the Arduino IDE for programming microprocessors on Arduino series microcontroller boards. Or in other words, Scratch For Arduino (S4A) is an integrated development environment based on block statements to develop programs that govern the control of a purely Arduino robot, with reactive capabilities to the environment based on what the sensors detect and different reaction options, depending on the actuators connected to the microcontroller outputs. It has never been so easy to program a robot!! From young children to users without programming knowledge can now do it thanks to S4A having a very simple and fun interface, but with the potential for creating serious and professional programs. Plus, it's free!

The best thing about Scratch For Arduino is that it allows us to program Arduino UNO microcontroller boards without having to know the syntax of any programming language, as we are talking about an Integrated Development Environment (IDE) that is based on block diagrams to create robot programs. Therefore, being multi-platform and free, it makes it ideal for that type of user who is a novice and inexperienced, but who is not afraid to venture into the world of industrial robotics and programming.

Scratch is a free and educational software aimed at learning computer programming without having to write code. It is done through blocks that you move and place in order with the mouse. But don't be fooled by its childish appearance, as it has all the statements like if-else, while, for, function calls, variables, etc. Very useful for younger students to start developing applications. Scratch For Arduino (S4A) is the original Scratch, in essence and form, but adapted to the capabilities of an Arduino microcontroller board, making its programming easier, faster, and more fun than in an Arduino IDE development environment. It is also free and has a very attractive interface.
