I have two projects to use Scratch and M5Stack named M5Scratch and M5bitLess.

To use these system, you can use physical sensors such like accel, button, temperature, audio, and so on.

Also you can use actuators such like display, LED, and so on.

This page introduce these projects.

M5Stack: Cute and Powerful microcontroler!!

M5Stack: All in microcomputer series.

Display, Button, Battery is packaged.

Extension mechanizm called Unit, Hat etc.

Development environment:

UIFlow 1,2: Block programming.

Micro Python: Python

Arduino IDE: C, C++

Hardware feature

CPU: ESP32 etc.

Display:

320x240TFT(Core,Core2)

80×160TFT(M5StickC)

135x240TFT(C Plus, C Plus2)

5x5 Full color matrix LED(ATOM Matrix)

Battery:

150mAh(Core)

390mAh(Core2)

80 or 95mAh(C)

120mAh(C Plus)

200mAh(C Plus2)

Network: Wi-Fi(2.4G) + BLE

Sensors: Accelrameter、Gyro、Button switch、Temperature, etc.

Audio: Microphone, Speaker, Buzzer.

I/O: Grove A(I2C), B(A/D,GPIO), C(UART), M-BUS etc.

Optional: Watch band, LEGO mount, Keyboard, etc.

What is M5Scartch for Scratch 1.4?

https://scrapbox.io/files/6674da0305aeb5001db2cc6c.svg

M5Scratch is program for interacting Scratch 1.4 and M5Stack.

To interact each other, it uses Scratch Remote Sensor Protocol.

Remote Sensor Protocol has two command.

sensor-update var_name var_value: send and receive data named var_name and value var_value.

broadcast event: send and receive event named event.

It's written in Arduino.

Project details is at M5bitLess: M5Stack x Scratch3 = So Fun!! and github.

What is M5bitLess for Scratch 3?

https://scrapbox.io/files/6674e2dfb37ce0001c670b7e.svg

M5Scratch is program for interacting Scratch 3 + Microbit More extension and M5Stack.

To interact each other, it uses Microbit More extension.

It's written in Arduino.

Microbit More extension is Scratch extension for interacting full micro:bit features.

It can use at Stretch3 server.

M5bitLess is program which emulate micro:bit features for Microbit More.

M5bitLess support blocks below:

Project details is at M5Scratch: M5Stack x Scratch1.4 and github.

Conclusion

I introduce M5Scratch and M5bitLess.

These systems can interact Scratch and M5Stack.

Using these system, Scratch can use physical world value such as accel, button, temperature, audio, and so on.
