ESP Configurator based on B4RSerializator
This tool replaces the browser based solution (https://www.b4x.com/android/forum/threads/esp8266-wifi-remote-configuration.68596/). It is simpler and much more powerful.

Node-Red MQTT controlling 8 relays ESP32
Here a sample program to control 8 outputs on arduino ESP32. The program use the MQTT protocol to exchange the data (really a single byte). By Node-red web interface the user set or reset the relay and the arduino send back the status as feedback.

Glossary for Arduino Development
This is not a tutorial for B4R. I think a glossary of terms might be useful for beginners to electronics and B4R. So I created my own list in GitHub to record the terms that I find need explanation.
