ESP8266
The ESP8266 module was produced by the Chinese-based Espressive Company in 2014. It is an electronic wireless communication chip that communicates with wireless electronic devices using the TCP / IP internet protocol. And it also contains microprocessors that are programmed for individual using.
The most significant features of the ESP8266 is cheapness and stability. It is sold for $ 3 and it can be found easily on the internet. Thanks to these, this kit has become very popular for wireless communication. The ease of programming and the small size make it even more common to use.
Purpose of ESP8266 Module
The wireless signal power of the ESP8266 Module has a range of 10-15 meters. In the other say, it is approximately 2 times stronger than the average modems of today. The primary priority required to use this module is the regional internet network because it communicates with the TCP / IP protocol.
After join the WIFI module to internet network, it gets its own private IP like other electronic devices. We can send signals to this device wirelessly from the local area network. If we want to control this device from anywhere connected to the internet, we can do this by port forwarding the modem where the ESP module is located.
Usage Areas of ESP8266 Module
The ESP module has two output. The remaining six ports are the supply voltage, ground and serial communication ports. We can wrote program in the microprocessor and we can make a personal project depend to the outputs are 1 or 0.
Programming should be done in LUA or C. The program "Ardinuo IDE" has become popular to program this module, and thanks to the various examples in the program, it provides easy for users who want to learn this electronic kit.
As an example of the ESP8266 project, we can use a wireless motor to move forward one of the output ports, the other port to move the motor back.
