Let's connect our ESP8266 to an Arduino board. You can use any Arduino. Just follow the following pin configuration. We are going to control an LED with the ESP8266. So the pin settings will be as follows:
| ESP8266 | Arduino |
| RX | 3 |
| TX | 2 |
| VCC | 3V |
| CH_PD | 3V |
| GPIO 0 | No connection |
| GPIO 2 | No connection |
We will use an app on our smartphone to control the LED turn on and turn off functions. Add an LED on pin 13 of the Arduino for avoiding complexities for the first time. First of all, download and install the Arduino IDE from https://www.arduino.cc/en/Main/Software. Now you need to install a library on your ...
