Hello guys. Welcome back to Techatronic. This tutorial will show you how to connect an Arduino board to a NodeMCU ESP8266 wirelessly using the NRF24L01 transceiver module. Thingspeak Server will receive the received data and upload it. This project is NRF24L01 Wifi Gateway with Arduino NRF24L01. Although NodeMCU allows us to monitor data globally, the…
Hey Guys, Welcome back to the techatronic. We are here with a very new article in this article we are going to make a tutorial on how to use stepper motor with ESP8266. A lot of tutorial about arduino with stepper motor but there is no tutorial for stepper motor with ESP8266. So that’s why…
Introduction Hey techies, welcome back to Techatronic. In this article, we are going to teach you how you can add wifi to Arduino and ESP266 programming. So for this, we are using an ESP 8266 module. You have to provide the SSID and password of your hotspot network in the code so that Arduino can…
Hello guys, we are back with another new post in the series of esp8266 led tutorials. We have already discussed some basic and interesting projects made using nodemcu. In this mini-project, we are going to teach you how you can control an LED using ESP8266 nodemcu. You can also check out more projects on IoT…
Introduction Hey guys, we are back with another new article in the series of ESP8266 tutorials. We hope that you are doing fine. Are you familiar with an RGB LED module? Basically,we can call it a combination of red, green, and blue LEDs, all are bound together in a single LED. It has four legs,…
Introduction Hello geeks, we are back with a new post in the series of nodemcu tutorials. Today we will learn how we can measure the temperature and humidity using a nodemcu board and a DHT11 sensor. If you are new to our website then please also check out our projects on IoT and final year…
Introduction Hello guys, hope you are doing fine. I am back with another new tutorial on nodemcu. In this article, we are going to learn how an IR sensor works with an esp8266 nodemcu board. Before starting, I want to give some details about the IR sensor, so basically it is an infrared sensor that…
Introduction Hello geeks, hope you are doing fine. Have you ever seen a seven-segment display? Well if you want to learn the working of a seven-segment display and to display the numbers on it then read the full article carefully. In this article, we are using a nodemcu development board to operate the seven-segment display….
Introduction Hi techies, hope you are doing fine. In this article, we are going to discuss the working of an RGB LED module and water level senor with the nodemcu. Well, what if we combine these two modules in a single project? So keeping this in mind we made a water level indicator system using…
Introduction Hey guys, welcome back to Techatronic. Hope you are doing fine. So today we will discuss the working of an esp8266 motion sensor. Well, I hope you know what a PIR sensor is. If not then don’t worry we will give you a brief introduction to it. Before starting I would like to give…
