Can I connect more than one phone to the arduino with the esp8266 and send information to the arduino?

Yes, you connect the devices to WIFI, put a server on the ESP, it should handle 5 simultaneous connections.

And how to do it, because I have an esp 8266 module, but I haven't used it yet so I don't know how it works or how to program it.

C++ do you know? Added after 1 [minute]: . Specifically what information? Which phone? What communication medium?

However, I am having trouble finding how to control the arduino with a smartphone using the esp8266 how to program the app in mit app inventor and what code to load into the arduino.

. So start with a C++, Arduino course from flashing an LED to more and more elaborate projects.

I've been with arduino for a good two years now and I don't need either the basics of programming or even more the basics of c++ because I've been programming games, apps etc for a good 4 years now. I've just never had to deal with the esp8266, or any other network module so I don't know how to connect it, what code to use and how to make in mit app invator an application that communicates with this module.

. And what specific model of ESP8266 module do you have? There are quite a few out there.

. If you are familiar with Arduino, you can program the ESP8266 in it too. Exactly the same environment, only you have to use the board manager to add something with ESP8266. See the article Uploading firmware to the ESP8266 section 3.3.

. You can also use the ESP-01 as a WiFi modem by connecting it over RX/TX to the Arduino. There are many examples on the web that describe such a mode of operation for the ESP-01.

Topic summary

Connecting multiple phones to an Arduino via an ESP8266 module for data communication is feasible by configuring the ESP8266 as a WiFi server capable of handling up to five simultaneous connections. The ESP8266 can be programmed using the Arduino IDE after adding the appropriate board manager. The ESP-01 model can operate either as a standalone WiFi server or as a WiFi modem connected to the Arduino via serial RX/TX lines. Programming requires knowledge of C++ and networking concepts. For app development, tools like MIT App Inventor can be used to create smartphone applications that communicate with the ESP8266 module. Resources and tutorials on uploading firmware and setting up the ESP8266 server mode are available online to assist with implementation.
