NodeMCU Projects

This section covers electronics projects based on NodeMCU ESP8266 board. The NodeMCU is basically an open source firmware, and also commonly used term for the popular ESP8266 Development Board, which is a low cost, development board designed for IoT applications. 

If one is familiar with using firebase to fetch and update data to real-time databases, then it’s known that it’s an annoying problem that the data will be destroyed when the NodeMCU resets. So, here, let’s learn how to overcome the problem with the help of LittleFS. This problem persists in Arduino as well, but to solve this in Arduino, we use EEPROM. It is a non-…

Blynk is an easy-to-use IoT platform using which you can easily build graphic interfaces for all your projects by simply dragging and dropping widgets. But the issue while using the Blynk app is the latency and limited energy. This problem can be solved by using a Blynk local server. Blynk local server provides unlimited energy and reduces latency.

India being a sports-loving country loves to watch sports in a group where the whole neighborhood comes and enjoys the sports together, be it cricket or football. But doing so, one of the problems we face is that the scoreboard on the bottom of our television screen becomes very small and hard to read. So, today we are going to build an IoT and Arduino-based IPL…

NodeMCU is a low-cost open-source IoT platform that initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module.

If you are getting started with IoT or microcontrollers in general, this development board is a fierce competition to everything that you’ll come…

Any electronics projects enthusiast has to first familiarize themselves with basic electronic projects. This includes trying to build simple devices and circuits using components like resistors, LEDs, diodes, transistors, etc. This forms a firm foundation in handling electronic components and helps to build complex projects later. Once familiar with the basics, one can move…

In this DIY tutorial, we are going to build an IoT-based GPS Location tracker using NEO-6M GPS Module. This Location Tracker Board consists of a NodeMCU, OLED Display Module, NEO-6M GPS Module, and 3.7 to 6V booster circuit. Here, we have also created a simple local webserver to display the location details. This webserver contains a link to directly check the location in…

RFID stands for Radio Frequency Identification, it’s a very simple and inexpensive piece of technology that can be used to make applications such as RFID Based Door Lock, RFID based Attendance System. If you search online for RFID Based Projects, you will find many projects that are associated with security and tagging which might make this interesting module appear…

Internet of Things (IoT) has seen exponential growth over the past couple of years. A new study from International Data Corporation (IDC) estimates that there will be almost 42 billion connected devices within the year 2025, generating over 80 zettabytes (ZB) of data. As the number of IoT devices grows; the amount of data grows, along with that, grows the need for superior…

When developing robotic projects, motors are one of the most important parts of the whole project and there is always a need for multiple motors. But GPIO pins of the Microcontroller boards don’t allow you to draw the amount of current required for a motor. That’s why the motor driver ICs are used. You can build a motor driver circuit by using some electronic components or…

“Good morning. It’s 7 A.M. The weather in Malibu is 72 degrees…” these were the first words of JARVIS when being introduced in the Marvel Cinematics Universe. Most Iron Man fans should be able to recollect this scene and remember that JARVIS was able to open a window (kind-of) in the morning and give updates on time and weather. In the movie, the window Glasses were actually…

Over the past few years, IoT (Internet of Things) devices have become an indistinguishable part of our daily lives. From smart homes, smart bulbs to smart appliances; creators and developers are incorporating this technology to create a network of connected devices that makes our day-to-day life a little more exciting. All this has been made possible because of the ease…

As the winter season approaches; comes that time of the year when the festival of lights is celebrated. Yes, we are talking about Diwali which is a true Indian festival celebrated across the globe.  This year, Diwali is already over, and seeing people firecrackers, I came up with the idea of building the Alexa based Voice Controlled Rocket Launcher or Igniter…
