How to track Location with NodeMCU without using GPS module Have you ever thought of getting your device’s location without using any GPS hardware? Sounds interesting!! Yes it is possible to get the location coordinates just using NodeMCU ESP board without any extra hardware. Here we will use ESP12E board to get live co-ordinates of our location. This becomes possible because of Google’s Geolocation API. So let’s see how this… |

DIY Wi-Fi Jammer using NodeMCU ESP12 Have you ever thought about jamming the Wi-Fi connection network? Now days Wi-Fi password hacking is very common, so by jamming the Wi-Fi network you can block or jam any Wi-Fi connection, and no one is able to connect to that Wi-Fi network even after knowing the password. This can be done with a tiny Microcontroller ESP12E, which is also referred as Wi-Fi module or NodeMCU… |

Alexa Voice Controlled LED using Raspberry Pi and ESP12 In previous tutorials we have seen How we can build an Amazon Echo Speaker and then how can we control any Raspberry Pi GPIO using Alexa Voice. Now we are making an IoT project to control home appliances from anywhere in the world using AlexaPi and ESP-12E (or any ESP board). Hardware Requirements Raspberry Pi with… |

IoT Based Electricity Energy Meter using ESP12 and Arduino We all know about Electricity energy meters which are installed in everyone’s house or offices to measure the electricity consumption. At last of every month, many of us get worried about the high electricity bill and we have to look at the energy meter once in a while. But what if we can monitor our electricity uses from anywhere in the world and get an SMS/E-mail when your… |

GPS Interfacing with NodeMCU: Getting Location Data GPS stands for Global Positioning System and it is used to find out location, altitude, speed, date and time in UTC. In this project we are going to interface a GPS module with NodeMCU. A simple local web server is created using NodeMCU and the location details are updated in that server webpage. Specialty of this IoT based project is we can check the location in Goolge Maps… |

IoT Digital Thermometer using NodeMCU and LM35 In previous Getting start with NodeMCU tutorial, we saw What is NodeMCU and how we can program it using Arduino IDE. As you know NodeMCU has Wi-Fi chip inside so, it can also connect to internet. It is very useful to build IoT Projects. We previously used ThingSpeak with Arduino to make IoT thermometer, but here we will create our own webpage to display temperature.… |

Interfacing LCD with NodeMCU without using I2C In this tutorial we will see how to interface NodeMCU with 16x2 LCD without using I2C communication. Here we will interface 16x2 LCD using shift register SN74HC595. We can also interface it even without using any shift register. We will see both kinds of interfacings in this tutorial. Main difference between both interfacings is the number of pins used in NodeMCU. … |

Getting Started with NodeMCU ESP-12 using Arduino IDE: Blinking an LED In this tutorial, we will learn about ESP-12 Wi-Fi module and how to program it using Arduino IDE. Then we will write a program to blink an LED with ESP8266-12. What is ESP8266 and NodeMCU? Most people call ESP8266 as a WIFI module, but it is actually a microcontroller. ESP8266 is the name of the microcontroller… |
