Written by Pavel Updated over a week ago. Did this answer your question?The circuit is very simple, we just need a Nodemcu board and a relay module to control home appliances securely from the smartphone through the internet. The circuit for this home automation project is very simple. We just need a relay module and NodeMCU board for this circuit. And we can control different home appliances from Blynk App.
Here I have used a 2-channel relay module but you can also connect 4-channel or 6-channel relay module with node MCU. To Create a new project in the Blynk app you have to give the project name and choose the device. After that Blynk app will send an Auth Token to the registered email id. For this smart home project, we need to install the Blynk library before programming the NodeMCU board.
Click Here to download latest Blynk library. Now click on the upload button to program the NodeMCU. You can also refer the tutorial video for creating the switch in the Blynk App. Here I have connected two AC lamps.
You can connect any other home appliances with this wifi relay module. Now we can control these AC lamps or any other home appliances from the smartphone. So this a very simple but useful internet of things project where I can control home appliances from anywhere if I have an internet connection on my mobile. Please do share your feedback on this NodeMCU project.

Smart Christmas tree controlled by your smartphone using blynk and esp Simplest wifi car controlled by your smartphone using NodeMcu esp and Blynk. Ok, I agree.Hey guys!! How are you? So it all started when I was wondering on how I can make my IOT project with Arduino and esp wifi module more compact and energy efficient and also a good IOT app with drag and drop facilities.
So it was a win -win situation for me as I could get hold of two exciting things for developing projects on IOT. With this awesome board and app in your hand the projects will become more compact and efficient!! The Only thing that will disappoint is you thatit works on 3V logic and you have to make arrangements when connecting sensors which work on 5V.
Blynk was designed for the Internet of Things. It can control hardware remotely, it can display sensor data, it can store data, vizualize it and do many other cool things. It's a digital dashboard where you can build a graphic interface for your project by simply dragging and dropping widgets.
It's really simple to set everything up and you'll start tinkering in less than 5 mins. Blynk is not tied to some specific board or shield. Instead, it's supporting hardware of your choice. There are three major components in the platform: Blynk App - allows to you create amazing interfaces for your projects using various widgets we provide.
Blynk Server - responsible for all the communications between the smartphone and hardware. You can use our Blynk Cloud or run your private Blynk server locally. Blynk Libraries - for all the popular hardware platforms - enable communication with the server and process all the incoming and outcoming commands. Now that we have some insights about the hardware and the app, we require the following components. This blynk app has set of library files which have to be included in the Arduino IDE environment before the project is executed.
Once the Zip file is downloaded ,extract it and individually copy all the folder to your libraries folder of your arduino. Oka simple answer is that it contains all the essential parameters which required to get the board booted and configured. All this boards listed have different configuration settings. Therefore we should also include NodeMCU's board configurations which typically contain the board architectureclock speed, baud rate etc.
If you want it in your email you can send it through email also. Now you will get your dashboard screen. In this project we add a simple button and then configure its settings as Digital GP13 pin. Refer Screen Shots. Note that since Blynk is free only to an extend, you have to choose your widgets wisely.
Now According to the Pin mapping diagram of Esp board, D7 pin is the 13th pin. So we would program the pin as 13 in the arduino code which we will shortly upload to the board.
Hi Vivek GR. Made it :- had some parts laying around and never tried to understood Arduino.Add the following snippet to your HTML:. If you want a NodeMCU device that could help you to control all your house electrical devices, then this will be your best guide. Read up about this project on. Hey guys!Sf droob7 bold font free download
During the making of this project, we tried to make sure that this instructable will be the best guide for you in order to help you if you want to make your own Smart house, so we hope that this instructable contain the needed documents.
We've made this project in just 4 days only, just two days to get all the needed parts and finish the hardware making and the assemble, then we have prepared the code to suit our project and start the testing and the adjustment.
A home automation system is simply a system that allows some users to have access to some electrical devices like lightning devices temperature monitoring doors control devices etc and this access is monitored through a basic application connected to the main system through a wireless or wired protocol, about the automation part, the system is able to adjust some environmental parameters automatically using some actuators and some sensors, for example the system can read temperature data from a temperature sensor and decides to turn on or to switch off an air-conditioner.
In our project we will create the main system which is an electronic circuit board based on a NodeMCU dev board which already has a wifi feature in it and this board will be surrounded by some electronic components like relays optocoplers LEDs and sensors, about the sensors we will use the motion sensor for an alarm detection, a DHT11 for temperature and humidity measuring and BH for light sensing.
About the actuators, we will control some V AC bulbs and a DC fan and all these actuators will be controlled through an android app that we have developed through Blynk application. So in this application I inserted some gauges to read the analog values from the sensors and I placed some buttons and sliders to control my outputs.
I used solidworks software to design this house model which already has sockets for the lightning spots the sensors and the fan, you can get the STL files from the download link down below, after preparing the design I have got my parts very well produced through a CNC laser cutting.Subaru tents
Moving to the electronics, I have created this circuit diagram that includes all the necessary parts required for this project. The annual production capacity issq. JLC is a professional PCB manufacturer featured of large scale, well equipment, strict management and superior quality. After making the circuit design I transformed this circuit into a customized PCB design with a house shape in order to get a beautiful PCB design when we order our circuit and to do so all what I need is to move to JLCPCB t he best PCB supplier in order to get the best PCB manufacturing service, after some simple clicks I have uploaded the appropriate GERBER files of my design and I set some parameters and this time we will use the black color for this project with a golden spots; just four days after placing the order and my PCBs are on my desktop.
You can also download the Gerber file for this circuit from the download link below in the case you want to place an order for the same circuit design. Soldering Iron Never touch the element of the soldering iron Hold wires to be heated with tweezers or clamps.
Always return the soldering iron to its stand when not in use. Never put it down on the workbench. Turn unit off and unplug when not in use. Once you run your Blynk application, you will find the selected NodeMCU board already online if you use the token provided by Blynk in your code.
Now all what we need is the final code that you can have for free from the download link below, the code is very well commented so you can understand it and adjust it for your own needs.
