This project is how to build a temperature and humidity wifi module. Not all the prep work steps for setting up the chip.You will need to load the LUA/NODEMCU software.You can find the latest LUA firmware at https://github.com/nodemcu/nodemcu-firmware...
Here I'll show you how to program small ESP8266EX and fix cheap relay module. If you just bought ESP8266 or NodeMCU and don't know what to do next, visit my Starting With NodeMCU - Blinking LED project. I also recommend to watch video bellow about this...
In this project, we are going to :Upload GPS data from ESP12E NodeMCU on thingspeakShow that data in google maps using HTML and Javascript.This hackaday contains:Step wise instructions of setting up GPS with ESP12E NodeMCU on breadboardStep wise instructions...
circuit part : The circuit is really simple all you need to do is connect the nodemcu Vin pin to Vcc of neopixel since we are using Vin pin of nodemcu for neopixel so don't use more than 5v as power for node mcu that's why i used usb cable...

Microcontrollers are at the heart of electrical goods that allow consumers to experiment with a variety of powerful projects. Many individuals are interested in purchasing the most efficient microcontrollers available. NODEMCU and Raspberry Pi Pico are...
The board’s controller is run by the NodeMCU which is connected to a N-Channel MOSFET for each color of the RGBW LED strip. Trimpot for brightness and 2 user buttons (that can be setup to change modes, possibly) were also added. A 5v regulator was then...

Hi all,Nowadays there are so many development boards and platforms announcing and getting cheaper as well. Of course IoT has an effect on it. For example, recently I got a ESP8266 based NodeMCU board. It is really cool and easy to use. There are so many...
NodeMCU is very popular in Home Automation. It’s WiFi capabilities and Arduino IDE support making it easier for IoT Applications. It is very tiny and has many Digital I/O pins, Serial Communication and I2C Communication. NodeMCU has a micro...
The box would include LED lightning and ventilation. It would regulate the temperature, humidity and it may filter out any smells.The aim is to make it as autonomous as it can get!The main controller would be an ESP8266 in the form of the nodeMCU platform....
