CoderDojo Trento Scratch

A collection of extensions we use in our labs.

Forked from OSEP Scratch

Most code is intact from the original, we only disabled things we don't use or couldn't compile.

CDTN KIDSUINO EXTENSION

Extension to run Keyestudio Kidsbits Kidsuino, in particular the set of sensors from Keyestudio Kidsbits Smart Engineering Kit

We are making this because original Keyestudio software only runs in win/mac with a driver, our extension should work also in Linux without driver installation.

MAKE SURE TO INSTALL LATEST FIRMWARE

NOTE: This software is IN PROGRESS, expect some bug.

WORKING THINGS:

• connection: ok
• firmware screen: when served locally with file:// I see weird characters, apart from that seems working
• digital read / write: some locking problems may arise, don't use concurrent code. TODO Kidsuino may have non-standard ports, check we cover them all
• analog read / write: some locking problems may arise, don't use concurrent code. TODO Kidsuino may have non-standard ports, check we cover them all
• servo commands: seems to work, we limited it to kidsuino channels 12 and 13.
• orange continuous 360° servo: works but commanding it through angles doesn't make much sense, maybe we should provide a proper command
• grey 270° servo: TODO check angles
• button: works but gives 0 on pressed and 1 when open, better to invert
• potentiometer: works
• touch sensor: works
• ultrasonic sensor: doesn't work
• IR sensor: to check
• steam sensor: works
• light: works
• buzzer: works
• integrated display: doesn't work
• joystick: doesn't work
• translation: to improve
• power: tried to connect via USB to laptop without batteries and put together buzzer + light + grey servo + orange servo without heavy loads, didn't fry anything (so far..)

Notes to myself to at least compile & build

Compile:

npm version: 8.19.4 node version: v16.20.2

npm install

npm run copy

Dirty things I did to make it compile:

rm -rf node_modules/openai/
rm -rf node_modules/scratch3_llmstudio/
rm -rf node_modules/scratch-vm/src/extensions/scratch3_llmstudio

source/scratch-vm/extension-support/extension-manager.js: disabled openai and llmstudio for build problems

deploy (sort of)

NOTE: for some reason osep scratch puts stuff in app instead of dist/

To put built website in app/

bash npm run deploy

To view the website and have Arduino working, you don't event need a server!  Just point the server to 

file:///PATH/TO/YOUR/cdtn-scratch/build 


### Develop

I still didn't understand how to properly run & develop

In case you really want to use a proper web server,  remember you need HTTP*S*


For now: 

```bash
npm run copy && npm run build

ORIGINAL OSEP STUFF --------------------------------------------------

Introduction

OSEP (Open-Source Extension Platform) Scratch is an open-source project running Scratch 3.0 GUI with official and experimental extensions. You can try out this project by going to https://estea8968.github.io/osep_web_serial/app/.

This project intends to comply with the 2019 Curriculum Guidelines of 12-Year Basic Education in Taiwan and to promote the teaching and learning of computer technology in high school and elementary school. In order to empower students to use innovative technologies to explore and solve problems in daily life, several extensions about open data, the Internet of Things (IoT), artificial intelligence, and others are included. Below is a list of extensions and their information.

Installation

This project requires you to have Git and Node.js installed. If you want to edit/play yourself, please follow these steps:

1. git clone https://github.com/estea8968/osep_web_serial.git
2. cd osep_web_serial
3. npm install
4. npm run copy (for Mac and Linux operating systems) npm run copy:win (for Windows operating system)

Running

npm start (for Mac and Linux operating systems)

npm run start:win (for Windows operating system)

Then go to http://localhost:8601/.

Conclusions

OSEP Scratch is a collective effort of open-source developers and educators. We welcome your comments and suggestions.
