I heard Lego's working with Scratch to make some LEGO Classroom sets. I figure if they made a LEGO Coding set with motion and sound motor bricks I can make a robotic tank with wheels that moves around the table. That would be cool!

And please fix the forum blocks

Now we can connect any Arduino Uno or Nano or Mega prototyping board for Scratch programming using PictoBlox.

It looks cool stuff.

Lots of ways to use an Arduino or other electronics with scratch.

1. Simplest is to run Scratch on a Raspberry Pi. You can then access the GPIO pins. If you still need to use an Arduino, just connect the pins together (not forgetting the 3.3v and 5v mismatch).
2. Snap4arduino is based on Scratch but is far more powerful and simple to use. You run firmata on the Arduino and control everything using the Snap blocks.
3. If you purely want to control robotics using Scratch you can use Scratch Link. Its very simple to control EV3 robotics projects.
4. The simplest single board computer to access is the Microbit. Again just load Scratch link and the Microbit control code. Scratch will then have access and control.

All the above are relatively simple and can be used in a children's code club.

There's no end of things you can do if you use GPIO to control things by running Scratch on a Raspberry Pi (simple and lots of examples out there). If you have 2 PIs then you run Scrach on one and the other can do whatever one want as you have WiFi, Bluetooth, I2C, and serial ports available in addition to lots of libraries. In addition to controlling and monitoring the physical world with Scratch you could always link to through to graphics programs such as Processing.

Lots of cool stuff.

Is there an Arduino Uno extension for Scratch 3? Where is it located?

I recall two year ago using Scratch 2 for Arduino Uno. It worked great. But now I can not find anything for extensions for Scratch 3.
Do I need to use Scratch 2?

Is their any books or information on this? I do not want to use Pictorial scratch unless it is my only option.

I greatly appreciate your help.

Michael

I see mention of Arduino here.

It's a very short topic! Make it more long!!!

I'm close to releasing a method of using Scratch 3 to control GPIO pins on a Pi - I should be able to adapt it to interface to Firmata running on Arduino - timescale estimate - a month

Hi Scratcher,
Were you able to adapt this to connect to Arduino using Scratch 3.0? Does anyone else have updates? I tried to use the ScratchX extension for Arduino but am struggling with the plugin, so I thought I'd look around for other options.

I made Scratch3 extension to connect Arduino named ‘Scrattino3’.

Download the FirmataStandard sketch on your Arduino and start Scrattino3 desktop app then you can connect and control Arduino from Scratch3 via USB.

@ykoubo Nice work

Take a look at this link. Scratch3 extensions for Arduino, Raspberry Pi, CircuitPlayGround Express, and ESP-8266.

It is really nice work! Can I use the Ultrasonic sensor SR04 with this tool?

No, you should need to change arduino program to use HC-SR04 with Scrattino..

I would recommend using a raspberry pi if you want to use scratch

can you help me, to tell me how to make arduino-scratch based application like pictoblox ? is there any github sources that I can fork or used as references ? thank you

Another option is Codecraft. Since we could not talk to our Arduino Uno Wifi Rev2 from Codecraft directly (MacOS Catalina), we just used the Codecraft editor to layout our sketch with scratch blocks. Then switched to code view, copied the text, pasted it in the Arduino IDE and uploaded it to Arduino, voilà!

No, they removed that feature I think
