Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Send and receive message remotely with ESP8266
The result is that the WiFiSecureClient doesn't work when used in the bot declaration, so I changed the variable to WiFiClient but I can't use the certificate, so I comment it out and ESP8266.h gives me a thousand errors due to lack of dependencies in its libraries. I should point out that I downloaded the entire project from the Arduino ESP8266, I don't know how to link all the libraries, so I simply took those from the ESP8266WiFi.

How do you determine what module/s do you have on your boards or vice versa?

Programming esp32
He meant the Arduino framework. There is an Arduino core for the ESP8266 so you can use Arduino’s IDE and libraries for the ESP with this core here

Help Needed: ESP NOW between ESP Wroom 32 DevKit and WeMos D1 Mini.
According to this link(https://github.com/esp8266/Arduino/issues/6174) WeMos can't receive broadcasts on SDK 2.2.1.

ESP8266 on ESPNow protocol power consumption/sleep mode
There are 2 ways to minimize power consumption while maintaining an active WiFi connection, but it's not a large power reduction for either mode. Look at Automatic Modem Sleep and Automatic Light Sleep here: https://github.com/esp8266/Arduino/tree/master/libraries/esp8266/examples/LowPowerDemo

lolin boards in close proximity are causing WIFI interferance
That's the Arduino (Uno) library. If you've correctly installed the ESP8266 package then it should be 3.(something-ish) for the ESP8266 version of the WiFi library. Current is 3.1.1 for the core files, and the WiFi is part of the core libraries. If you have your compile options set for verbose then you should see it doesn't access that old Arduino WiFi library.

Is there any way to get a low battery alert from a D1 mini?

Any good/worthwhile Camera sensor modules for arduino/pico for still photography?
You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.
- I am trying to write to an SD card, it "works" but I can only find the file on PC if I use data recovery software?

ESP32 memory corruption
Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

The Nano ESP32
That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.
The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.
Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32
Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

Arduino Uno R4 WiFi
They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]
It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]
