Tx: connect to the Rx of the microcontroller(Arduino) to establish serial communication.GPIO0, GPIO2: General purpose input/output pins.RST: Chip Reset pin – Active LOW, when it pulled LOW it Resets the module.connect it to a logic value HIGH to allow the module to boot up. CH_PD: chip enables pin – Active HIGH.GND: -ve pin, connect it to the ground of your circuit.don’t connect it with a 5V source it will get damaged. I encourage you to look at each one specifications and features to choose the most suitable one for your needs. There are a lot of ESP wifi modules models out there, which one should I choose?! Well, almost all the ESP family wifi modules out there will do the job well but each one has its own features and specifications. So, we will use the ESP8266-01 wifi module to add the wifi feature to our tiny Arduino board. And according to the incoming data, the Arduino board will take some actions like turning on the bulb, turning off the TV and in this part, we will use:Īs we stated before, we need our Arduino board to get connected to the Internet but the Arduino Nano the version which we are using today doesn’t have that feature. The web page sends some orders to the ESP8266-01 which is working as a web server connected to the Arduino board.
We will build a simple web page that will work as a control panel for the user allows him to control any home appliance connected to our system.
