The ESP8266-01 is a low cost and user-friendly device to provide internet connectivity to your projects. This module can be used as a Wi-Fi hotspot or can connect to any WI-Fi network. We use this module to make our projects IoT enabled and gather and process the data easily. The ESP-01 can also fetch data from the internet and it can be used in your project. Its most important feature is that it can be programmed with Arduino IDE, which makes it a lot more user friendly. One drawback of this module is that it only has two GPIO pins, so you have to use it along with another controller like Arduino, or go for other modules like NodeMCUESP-12, or ESP-32. It finds uses in Portable Electronics, Robotics, Home Automation, Wireless Data Logging, etc.

To use the module, power it with 3.3V supply, take caution as anything over 3.7V will damage the board. Connect the transmitter and receiver pins to respective pins on the Arduino board or you can use the FTDI board that supports 3.3V programming. You can use it as Access Point, Station, or on both Modes to connect to the Internet.
