  ### 3. S4A

**Rating:** 5.0/5.0 stars

**Reviewed by:** PABLO A. | Técnico de redes y microsistemas informáticos., Mid-Market (51-1000 emp.)

**Reviewed Date:** November 25, 2018

**What do you like best about S4A?**

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!

**What do you dislike about S4A?**

Actually, there is nothing I don't like about Scratch for Arduino (S4A), but to mention something, the Arduino hardware units are expensive and hard to find in local stores.

**Recommendations to others considering S4A:**

S4A is free, very fun, very easy to use, and develops the abilities of both novice users and younger users, allowing them to create functional programs with Arduino hardware.

**What problems is S4A solving and how is that benefiting you?**

It has been used to teach young students to take their first steps in programming, to develop programming, to study different statements and code blocks, to compile programs, and to debug errors after putting different robotic projects into operation.

  ### 4. Scratch For Arduino

**Rating:** 5.0/5.0 stars

**Reviewed by:** KEVIN A. | IT ADMINISTRADOR, Mid-Market (51-1000 emp.)

**Reviewed Date:** November 22, 2018

**What do you like best about S4A?**

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.

**What do you dislike about S4A?**

The worst thing about Scratch For Arduino is that it requires purchasing hardware for us to program it, and this hardware is hard to find in regular stores, and it's also somewhat expensive. But as for the program named Scratch For Arduino, it works perfectly and I don't see any drawbacks.

**Recommendations to others considering S4A:**

Highly recommended. Free, easy to use, enhances the student's creativity!

**What problems is S4A solving and how is that benefiting you?**

Scratch For Arduino is used in our company to carry out projects that require articulating arms or starting motors, such as the operation of a hydraulic dam that activates when there is no light. It is free and delights our younger or inexperienced clients. They learn quickly and use Scratch For Arduino very well.

  ### 5. Scratch For Arduino

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Education Management | Mid-Market (51-1000 emp.)

**Reviewed Date:** November 12, 2018

**What do you like best about S4A?**

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.

**What do you dislike about S4A?**

The worst part is the expense required for Arduino materials so that the programs we are going to create are useful for something. Sometimes S4A does not recognize the Arduino UNO board and you have to unplug and plug it back in. Other than that, S4A does not present any issues, quite the opposite.

**Recommendations to others considering S4A:**

Very interesting option to introduce novice users to the world of programming, application development, and programming robots and microcontroller boards, with connected sensors and actuators. Plus, it's free.

**What problems is S4A solving and how is that benefiting you?**

It is used in Technology and Robotics lectures with students aged between 14 and 16, for whom an IDE environment in Arduino is still very complicated because they have never had contact with programming languages. However, they are old enough to understand the basic control statements of programming, while they learn, have fun, and enhance their creativity by making excellent robotics projects that have even won them awards, such as a greenhouse that regulates the temperature and waters the plants intelligently based on the values read by the sensors connected to an Arduino UNO board.
