keyestudio Scratch for Arduino Starter Kit

Introduction

Scratch is a free programming language, which is used in more than 150 different countries and available in more than 40 languages. Scratch helps young people learn to think creatively, reason systematically, and work collaboratively — essential skills for life in the 21st century. It is wide applied to teaching process about programming in schools. In below projects, we are going to combine Scratch with Arduino to make more interactive and interesting projects. Students and children can program themselves by Scratch to make Arduino perform or use Arduino to get data measured by external sensors; therefore, they can create their own interactive stories, games, and animations. Using Scratch to program is very easy. A 6-year-old kid, under guidance, can build a complete program according to an sample. During that process, kids have no need to know English or Chinese, and they have a chance to enjoy graffiti, sound recording and finding pictures.

Software Installation

Arduino Introduction

What’s Arduino? Arduino is an open-source hardware project platform. This platform includes a circuit board with simple I/O function and program development environment software. It can be used to develop interactive products. For example, it can read signals of multiple switches and sensors, and control light, servo motor and other various physical devices. It’s widely applied in robot field.

Install Development Environment Software IDE

The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software. This software can be used with any Arduino board. Refer to the page https://www.arduino.cc/en/Guide/HomePage for Installation instructions. Or just look at our instruction. First, download Arduino development software, click below hyperlink: https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x Downloaded file is an arduino-1.5.6-r2-windows.zip compressed folder, and unzip it to your hard drive.

Double click Arduino-1.5.6 .exe. and select “I agree”.

Choose the components to install and click “Next”.

Choose the installation directory (we suggest to keep the default one) and then click “Install”.

The process will extract and install all the required files to execute properly the Arduino Software (IDE), and click Close.

Below is how Arduino 1.5.6 looks like.

Install Arduino Driver

For different operating system, there may be slight difference in installation method. Next, let’s install Arduino driver for your Arduino board with WIN 7. When you connect Arduino Uno to your computer the first time, right click “Computer” —> “Properties”—> “Device manager”, you can see “USB2.0-Serial”.

Right click on the "USB2.0-Serial" port and choose the "Update Driver Software" option.

Next, choose the "Browse my computer for Driver software" option.

Finally, navigate to and select the Uno's driver file, named "usb_ch341_3.1.2009.06", located in the "Drivers" folder of the Arduino Software download, click “Next”.

The below dialog boxes automatically appears if you have installed driver successfully and click “Close” to finish.

You can check that the drivers have been installed by opening the Windows Device Manager. Go to “Device manager” again. Right click “Computer” → “Properties”→ “Device manager”, you can see CH340 device as below figure shows, also the COM port info.

Introduction to Scratch and S4A Software

Scratch is a simple programming tool aiming at teenagers. Its advantage is: users can be those who even don’t know English, neither keyboard. Commands and parameters of program are displayed by building block module. In order to programming, just drag the blocks to formula bar. Almost all children fall in love with this software at first sight and their desire is aroused to program.
In this kit, we use S4A software as development environment. S4A 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.
S4A 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 10, 11 and 13) and 4 special outputs. S4A allows you to control as many boards as USB ports you have.

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 S4A. First, Open the firmware file (S4AFirmware15) from the Arduino environment.

In the Tools menu, select the board version and the serial port where the board is connected.



Click Verify

to check code.

Load the firmware into your board through File > Upload

.

Done uploading as shown below.
