An S4A program to control a light-sensor Theremin, with record and playback capabilities. Arduino objects offer blocks for the basic microcontroller functionalities, analog and digital writes and reads, and also for higher level ones.

You can find blocks to manage standard and continuous rotation servomotors:. In S4A, an Arduino board is represented by a special kind of sprite. The Arduino sprite will automatically find the usb port where the board is connected. It is possible to connect to multiple boards at the same robot arduino nano driver windows xp download by robot arduino nano driver windows xp download adding a new Arduino sprite. Other boards haven't been tested, but they may also work.

Components have to be connected in a particular way. S4A allows for 6 analog inputs analog pins2 digital inputs digital pins 2 and 33 analog outputs digital pins 5, 6 and 93 digital outputs pins 10, 11 and 13 and 4 special outputs to connect Parallax continuous rotation servomotors digital pins 4, 7, 8 and S4A is backwards compatible with Scratchso you can open Scratch projects in it. However, you won't be able to share your projects on the Scratch community website because doing so goes against the Scratch terms of use.

Take in account that this compatibility doesn't work both ways, so you won't be able to open an S4A project from robot arduino nano driver windows xp download the original Scratch. Using a PicoBoard along with an Arduino board is also supported. S4A interacts with Arduino by sending the actuator states and receiving sensor states every 75 ms, therefore the pulse width needs to be greater than this time period.

The data exchange follows the PicoBoard protocol and needs a specific program firmware to be installed in the board. Please refer to the Downloads section for further instructions on how to do so.

These materials were created and used by our team in an actual S4A course at the Elisava School of Design Barcelona in Here you'll find basic S4A examples, complete with the Arduino schematics and an. Some of the following demos are in Catalan or Spanish, but the images pretty much speak for themselves. Some of the videos have English subtitles as well. A robot with a rotative camera, distance sensors and a remote control. This video serves as an introduction for the S4A workshops given at Citilabbut you'll find a couple of demos of what can be achieved with our software.

A blind curtain controller. You can download it here or by scanning the QR code below:. The Android application uses a very simple protocol we developed on top of the Scratch HTTP message protocol, so it is also possible to interact to S4A from a browser or any other network enabled application.

You will first need to enable the remote sensors option in S4A right click on robot arduino nano driver windows xp download "Sensors" block. Send the value of a remote sensor for instance, the client's accelerometer, mouse position, etc: Update an S4A variable: S4A robot arduino nano driver windows xp download in the three major consumer operating systems.

Download and install the one that fits your configuration:. This firmware is a piece of software you need to install robot arduino nano driver windows xp download your Arduino board to be able to communicate with it from S4A. If you are a Microsoft Windows user, you may need to install the Arduino drivers into your computer:.

S4A is free software distributed under an MIT license. Since Scratch is actually a Squeak Smalltalk image, all of its code is actually shipped with the final user version itself. You're now in front of a classic Squeak 2. However, in the final user version some code has been compiled and you'll be missing several variable and message argument names, which is why we are also providing you with a clean source code image for developers, downloadable here:.

Since our VPS provider may sometimes be down, we've set up an alternative location for all files, including old versions:. In fact, our "firmware" is just like any other Arduino sketch, so there is no risk at all. Of course, you can upload other sketches to the board and then upload the S4A firmware again when needed.

There is currently no way to compile code into Arduino binaries. It must be said that S4A was conceived as an improvement of the older versions of Scratch the ones that were developed in Smalltalkto make learning how to program real-world objects easier to everyone, specially to children, by dealing with these real objects in the same way they'd deal with Scratch "normal objects", so they can interact between them. In other words, it was not made to program the board directly, but to help learn programming and electronics at the same time.

Still, if what you want is to just get rid of the USB cable, we recommend you use a wireless device like XBee. Pin configuration is hardcoded both in the firmware and in the source code of S4A, and the way S4A is made does not allow to change source code "on the fly".

So, until we find a robot arduino nano driver windows xp download way or enhance the communication protocol between the board and the program, the only way to customize the pinout is by changing both S4A source code and the firmware. Which boards does S4A support? S4A works on the three major consumer operating systems: So yes, it will most probably work on your PC. The Debian version of S4A is packaged only for i systems.

To get it working in a bit version, you need to follow the following steps in a terminal, as root:. To install S4A, you'll need to change this option to "Anywhere". Make sure you have uploaded the latest S4A firmware to the board before starting S4A. To do this you'll need the official Arduino IDE. Please follow the instructions on the Downloads section in this website.

This is a common known issue in Windows operating systems. Try stopping the connection with the board right-click on sensor board in S4Aunplugging the USB cable, plugging it again and restarting the connection. If the program still does not detect the board, there may be a conflicting serial COM port causing S4A to hang when trying to open it. To avoid this, try opening it directly right-click on sensor board and select serial port or changing the assigned Arduino COM port through the Windows Device Manager.

While working at Citilabshe developed her first final thesis, which consisted in building a framework to work with Arduino boards from within the Pharo Smalltalk environment. Later on, she used this project as the basis on which S4A was written.

While there, he had the opportunity to enter Citilab through an internship, where he later developed S4A, his final thesis. Joan is a biologist who, in his early years, worked robot arduino nano driver windows xp download the field of ecology. The robot arduino nano driver windows xp download to analyze the generated information and collected data drove his approach to computing.

He enrolled to his first programming course inwhen computers where still programmed by means of punch cards. His main work in Citilab has been related to the field of training in two areas: Jose studied advanced telecommunications engineering, but started working at a publishing firm before completing his degree.

During his time at the company, he worked on programming a wide variety of applications. At Citilabhe discovered Scratch and Smalltalktaking up part of his programming work again. Later on, he joined different projects that aim to establish closer contact between users and programming. He currently leads the Technological Robot arduino nano driver windows xp download Research team Edutec. He learned Smalltalk at a course given by Jordi Delgado at Citilab inwhere he was later hired to build an online programming school.

Since then, he's been involved in several programming projects in Citilabincluding a social knowledge management system and different educational applications. He spends robot arduino nano driver windows xp download of his time divulging, spreading the word of and programming in Smalltalkan amazing programming language that, you know, everyone should be using.

Frederique Pinson - French fr. Added a "check for updates" option in "Help" menu, from now on there is no need to visit website to check for new versions Language is now detected upon first launch when Scratch.

Also saved in same file if changed from language menu Robot arduino nano driver windows xp download port where a board is connected opens correctly when S4A is launched Fixed bug in Windows version, in which title bar didn't show the name and version of S4A when launched Version 1.
