WiFi Controlled LED Using NodeMCU

Hi friend welcome to secret of electronics. In this article I will tall you how to make wifi controlled LED using nodemcu.

Component list:-

1. NodeMCU

2. 3V LED

3. 220 Ohm Resistor

4. Breadboard

5. Jumper Wire

NodeMCU is a devlopement board this board comes with wifi module. So we can use this board in our iot and wireless project. We can easily program this board by arduino IDE. We can also program this code by micropython. but is we program this board by micropython than first we need upload firmware in this board. in this project i am using arduino ide so we not need to upload any firmware.

if you are using this board first time than first you should need add this board in your ide. if i dicuss how to add this board in your ide than the article will very long. so we providing a link below :-

click here for how to add this board in your ide

you can download this project code by given below link:

Click here for this project code

After downloading open this code in your arduino ide change the ssid and password with your ssid and password. After Changing save this code and compile this code after successfully compiletion upload this code in your NodeMCU board.

Connect all component together according above diagram.

connect your nodemcu board with your pc or laptop by usb cable. Open serial moniter in arduino ide same time later in serial moniter you can see a ip address note this ip and open your smartphone browser .

For turn on led type

your_ip/on

For turn off led type
