DumbDisplay play online

DumbDisplay is a simple Bluetooth / USB Serial Terminal (monitor / plotter), extended to act as a "dumb" display (as well as a little bit of inputting means)
for Arduino / ESP8266 / ESP32 -- using a Arduino library (https://github.com/trevorwslee/Arduino-DumbDisplay)
for BBC Micro:bit (V1) -- using a MakeCode extension (https://github.com/trevorwslee/MCExtension-DumbDisplay)

For Arduino UNO, DumpDisplay is tested to connect via
Bluetooth (with HC-06)
USB (OTG)
USB via DDWifiBridge (a Python program)
For ESP8266, DumpDisplay is tested to connect via
Bluetooth (with HC-06)
USB (OTG) (CP2102)
USB via DDWifiBridge
WIFI
For ESP32, DumpDisplay is tested to connect via
Bluetooth
USB (OTG) (CH340 and CP2102)
USB via DDWifiBridge
WIFI
For BBC Micro:bit (V1), DumpDisplay is tested to connect via
Bluetooth LE
USB (OTG)

The idea of using DumbDisplay as a display is that you can defer connecting real output gadgets to your Arduino until later stage of your experiments.

Specifically, for Arduino / ESP8266 / ESP32 -- DumbDisplay can be used as virtual output gadgets in place of the real ones
LED-grid layer
LCD layer (text-based and graphical)
7-Segment-row layer
Micro:bit like layer
Turtle-like layer

Moreover, with the layer "feedback" mechanism -- which allows user-click "feedback" be routed to Ardunio code -- Dumbdisplay can be treated as very simply input gadgets as well.

DumbDisplay also features the "tunnel" mechanism that aids microcontroller programs to get simply data (include simple JSON data) from the Internet.

Notes on DDWifiBridge:
* DDWifiBridge is a simply Python program comes with the DumbDisplay Arduino library
* Proxying USB connection to your desktop, DDWifiBridge bridges between USB and WIFI connection to DumbDisplay
* This way, there is no need of Arduino UNO to have special add-on in order to connect to DumpDisplay


Hope this little app helps.
