S4. AAbout S4. AS4. A is a Scratch modification that allows for simple programming of the Arduino open source hardware platform.
It provides new blocks for managing sensors and actuators connected to Arduino. There is also a sensors report board similar to the Pico. Board one. The main aim of the project is attracting people to the programming world. The goal is also to provide a high level interface to Arduino programmers with functionalities such as interacting with a set of boards through user events. The interface. An S4.
A 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 S4. A, 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 time by just adding a new Arduino sprite. Technical details.
Supported boards. S4. A works with Arduino Diecimila, Duemilanove and Uno. Other boards haven't been tested, but they may also work. Connectivity. Components have to be connected in a particular way. S4. A allows for 6 analog inputs (analog pins), 2 digital inputs (digital pins 2 and 3), 3 analog outputs (digital pins 5, 6 and 9), 3 digital outputs (pins 1. Parallax continuous rotation servomotors (digital pins 4, 7, 8 and 1.
You can manage a board wirelessly by attaching an RF module to it, such as Xbee. S4. A allows you to control as many boards as USB ports you have.
Compatibility. S4. A is backwards compatible with Scratch, so 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 S4. A project from within the original Scratch. Using a Pico. Board along with an Arduino board is also supported.
Protocol. S4. A interacts with Arduino by sending the actuator states and receiving sensor states every 7. The data exchange follows the Pico. Board 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.

Here you'll find the detailed steps to get it up and running. Installing S4. A into your computer. S4. A works in the three major consumer operating systems.
Download and install the one that fits your configuration: Installing the Firmware into your Arduino. This firmware is a piece of software you need to install into your Arduino board to be able to communicate with it from S4. A. Download and install the Arduino environment by following the instructions on http: //arduino.
Main/Software. Take in account Arduino Uno requires at least version 0. Download our firmware from here. Connect your Arduino board to a USB port in your computer. Open the firmware file (S4. AFirmware. 16. ino) from the Arduino environment.
In the Tools menu, select the board version and the serial port where the board is connected. Load the firmware into your board through File > Upload. Arduino drivers. If you are a Microsoft Windows user, you may need to install the Arduino drivers into your computer: Arduino drivers for Microsoft Windows. For Developers. S4. A 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. How To Download Music On Samsung Behold 2 Hard. To access it, just shift + left click on the S4.
A . You're now in front of a classic Squeak 2. Browser, Workspace and all tools you're used to. 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: S4. A Developer Edition. Alternative download site. Since our VPS provider may sometimes be down, we've set up an alternative location for all files, including old versions: S4. A Dropbox folder.
Frequently Asked Questions. General questions.
Can the S4. A firmware damage the board? In fact, our . Of course, you can upload other sketches to the board and then upload the S4. A firmware again when needed. Can the S4. A programs be pushed into the Arduino board?
There is currently no way to compile code into Arduino binaries. It must be said that S4. A was conceived as an improvement of the older versions of Scratch (the ones that were developed in Smalltalk), to 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 .
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. Can I change the pinout configuration?
Unfortunately, no. Pin configuration is hardcoded both in the firmware and in the source code of S4. A, and the way S4. A is made does not allow to change source code . So, until we find a better way or enhance the communication protocol between the board and the program, the only way to customize the pinout is by changing both S4. A source code and the firmware. There is a Spanish unofficial guide available here (thanks to Borja P.
Other boards haven't been tested, but they may also work. Will S4. A work on my PC?
S4. A works on the three major consumer operating systems: Microsoft Windows, GNU/Linux and Mac. OS. So yes, it will most probably work on your PC. Work At Home Opportunities Executive Order. Installation troubleshooting. I can't install it on 6. Ubuntu/Debian. The Debian version of S4.

To install S4. A, you'll need to change this option to . To do this you'll need the official Arduino IDE. Please follow the instructions on the Downloads section in this website. Been there, done that. Board still not detected.
This is a common known issue in Windows operating systems. Try stopping the connection with the board (right- click on sensor board in S4.
A), unplugging 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 S4. A 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.
