I have an Arduino Mega 2560 board and an ESP8266 WiFi Module. I need to connect my Arduino board to my Firebase database, so I can get data from my database to the Arduino.
When I include the <FirebaseArduino.h> library, there is an error saying
Error compiling for board Arduino/Genuino Mega or Mega 2560
Isn't it possible to connect an Arduino Mega board to Firebase?
I think you need to add ESP8266.h header file to the project.

I want to connect my arduino nano with my ESP-32 (in order to use it for wireless communications).
I got this ESP board (see pic).
Any idea how I can connect it? I can't find any documentation for the pin on this board.
Check this,

You can directly use ESP32 to perform the same functions of arduino.
Is it possible for an Arduino Uno subscribe/connect to MQTT Broker (Mosquitto) without using Ethernet Shield or Wifi Shield?
Actually I have a Wifi module (ESP8266) with me, unfortunately it won't allow me to upload sketch and I keep getting error error: espcomm_upload_mem failed
When I interface Arduino Uno with ESP8266 Wifi Module, I construct like this:
And I have included Generic ESP8266 Module in board manager.

Of course you need a network to handled a PubSubClient.h library for your MQTT Broker.
I keep getting error error: espcomm_upload_mem failed
I think you have something wrong about the wired or the code, can you post your schematic and your code into your question? so that i get why have this errors.
see this library.
I am using ESP8266-01 with Arduino Uno... I am able to compile example code of ESP8266 with Generic ESP8266 module board with arduino ide but unable to upload it to Uno...., it is giving an error: espcomm_upload_mem failed while uploading the code to Uno
How the code is compiled is based on the board you have set in the Arduino IDE.
Before you compile and upload, have you switched the IDE to use an Uno board?
In the Arduino IDE try:
Tools | Board | Arduino Uno
Esp8266 generic example will not run on Arduino Uno. Possibly your device is selected as Esp8266 from Device Manager as gurus said. What you need to run Uno with Esp is writing Esp8266 serial controller to Uno. Here is the sample. Good luck.
Can I connect a sensor or a LED to HM-10 Bluetooth Module without Arduino?
If yes, how to upload a code to it ( not an AT commands)?
HM-10 at most cases can't work as standalone device, It needs an Arduino or microcontroller and they can do the hard work(processing and doing commands) while HM-10 is the gateway for them to communicate with other devices using Bluetooth.
I have an arduino mega ADK, with usb port, and an arduino uno.
- On the arduino uno, I put a xBee shield with the wifly module for connect to the internet.
- On the arduino mega ADK, I put the TinkerKit! shield.
I need to use both : xBee shield and TinkerKit!. and the single way i found, is to connect the arduino uno to the arduino mega ADK by USB wire (the wire is the one I use to connect an arduino to my computer).
Do you think it could work ? If yes, How can I get what is writting on the outpu of the arduino uno ? If no, is there an other way to do what I need ?
yes, it can be done, but is is way more easier to use directly the Hardware/Software Serial. Even if you get iw work, it will be a serial simulation over usb..
So using USB is just a layer of complexity that can break, and nothing more.
