First, do I need 2 Arduino Unos with ESP8266 module installed to communicate with each other?
I want to transmit ultrasonic value from 1 Arduino Uno to another. Thank you for answering my question.
There is no need of an Arduino to comunicate 2 ESP8266 modules. Maybe you can read that ultrasonic value with the ESP and send it to another or to the internet. Check this tutorial maybe will be useful.

I want to program a simple Webserver with an ESP8266 but I want to connect the ESP8266 to an Arduino Mega. I want to connect a LED and a Sensor to the Arduino and control the LED and read the sensor data via the ESP8266 Webserver.
I am a beginner and dont want too complex solutions. It's just a simple school project.
For the Webpage I am sending just some HTML Code, I do not use Blynk or anything like that.
My question is how can I connect the ESP8266 to the Arduino and control it's pins?
There is a million ways to connect an ESP to an Arduino.
Without any shields or perihperals you can basically use any wired bus that does not require transceivers.
For example I2C or SPI.
With shields or peripherals you can use CAN, LIN, RS232, Ethernet, WIFI, Bluetooth, radio, optical and audio transmission... The list is endless.
You can of course read a sensor with the ESP so an Arduino Mega is not really necessary.
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.
I hav tried connecting through serial communication. But i hav a problem with that. I think AT commands can be also given through I2C communication. But I am getting stuck at some point. Can anyone help with step by step instructions to make a connection? thank you
You need mainly 3 pins to connect Arduino Uno and GSM Modem.
RxD
TxD
GND
This Tutorial will clear all your doubt about hardware connection and also about Arduino sketch you have write.
this please.
How do you connect or create the interface from an xbee all the way to the web for it to work. This is a sample description.
web←ethernet shield←arduino←xbee --xbee→arduino→led
Can somebody please give me a sample code for this to work?
the ethernet shield doesn’t pass the ICSP pins through to the next layer hence the XBee shield has nothing to plug into.
try this:

The Sparkfun Xbee shield works fine. It doesn't use the ICSP pins.
I have a few questions about rpi and arduino.
1. Is it possible to provide arduino and rpi two-way communication? (Sending data from the sensors to the Arduino and from arduino to RPI and processing information on RPI).
2. Can i use sensors from Arduino on RPI?
3. Can I programming RPI using C++ (such an as Arduino)?
Yes, checkout the ArduPi project. Serial communication (a USB cable) between the two is a fairly simple way to get started. It provides bi-directional communication between Raspberry and Arduino. And yes, you can compile C/C++ on the Raspberry Pi (but in most cases, you cannot directly reuse C/C++ for Arduino directly on the Pi, as it might use some special .h files not available on the Pi).
Yes it can. Just use I2C Bus (or Two-Wire). By TWI You can easily communicate Rpi and Arduino.
You can directly read the Arduino through the USB serial port. There is a Linux board I came across that you plug directly on top of your Arduino like a shield (It's called the Rubix) .
Of course it is, Uart , I2C or SPI.
I highly recommand Uart.
1.The library GPIO has demo of Uart Communication.
2.You can use USB to connect the serial port.
you can follow this tutorial to make it run

Yes you can communicate using I2C. There should be a wired connection between RPi and Arduino to communicate using I2C. If you wanna try wireless communication you can use ESP8266 13 arduino wifi shield.

Otherwise you can use a ESP8266 module replacing arduino and you can communicate bidirectionally using wifi.
Most sensors that work with the Raspberry Pi, also work with Arduino and other boards like it.
