For the ESP32 Blynk 2.0, please refer to the following video
https://youtu.be/Vgyj3cCAioI
Important points:
In code, you have to update only the BLYNK_TEMPLATE_ID \u0026 BLYNK_DEVICE_NAME as shown in the video.
Keep all the 9 files (.ino \u0026 .h) in the same folder.
You can only control the appliances if the WiFi is connected.
Please take proper safety precautions while working with high voltages.

During this internet of things tutorial video, I have explained all the steps to configure the new Blynk 2.0 platform for any ESP8266 home automation system. Also explained how to create templates, and add Datastreams (Virtual Pin) in the Blynk IoT cloud account. If the NodeMCU connected with WiFi then you can control the relays from anywhere in the world. And you can also monitor the realtime feedback in the Blynk IoT applications. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.

2-CH RF Wireless RC Relay Module: DC Motor Forward/Reverse Direction Control


This video demonstrates the simple way to control the direction of a DC motor which in this case a 12V car power window. Two relays were used to build the required circuit and in this video, a 2channel RF wireless remote control relay module was the perfect choice to do that. The connection is so simple; everybody with or without basic electronic knowledge can build the circuit in minutes and use it right away. This video intends to give some basic idea on building a bidirectional motor control circuit and you can apply it in your own project/application.
For those who are having trouble catching up the connection for 2direction motor control in the video, you may refer to this diagram: https://goo.gl/Fnsf4B. Just ignore the Arduino side as the relays themselves will be activated through button click. However, if you in case to build Arduino controlled 2direction motor control, then this may be the diagram you are looking for.
The Arduino code to make the motor run forward and backward continuously with 2 seconds of duty cycle: https://goo.gl/iN7sfr.
Circuit diagram: https://goo.gl/rxqDrg.
Demonstration video: https://youtu.be/OzlJ9E2_aSo.
The Arduino code to make the motor interact with input from serial communication: https://goo.gl/ZqecCP.
Circuit diagram: https://goo.gl/u5AQKg.
(Updated on 26 Feb 2019): For 8 channel relay module: https://goo.gl/admrPB (pin connections are described in the code introduction).
(New Updated on 29 November 2017) The Arduino code to make the motor interact with input from serial communication + manual push buttons: https://goo.gl/iPjDhZ, with help of circuit diagram: https://goo.gl/fLeJpF.
For those who don’t want Arduino in the diagram, refer this circuit: https://goo.gl/kjjoKU, with truth table included.
(Updated on 1 March 2018) For those who are interested to use limit switch in the circuit (such as for linear actuator motor control), refer this circuit: https://goo.gl/C5ATjB for LOCAL controlled single limit switch version and this circuit: https://goo.gl/83mynM for LOCAL controlled double limit switch version. And for REMOTE controlled double limit switch version, see here: https://goo.gl/gZVRp2. Hope that helps 🙂
(Updated on 29 November 2018): If you want to make the motor turns forward until a limit switch is pressed, then wait for let say 1 hour before going reverse until another limit switch is found, then wait 1 hour again and repeat the process again like more or less shown in this video: https://youtu.be/gnL5j3eTRU, here is the code: https://goo.gl/dnHLkR.

Home automation using NodeMCU and Blynk App – IOT based Project


In this IoT based project, we will learn how to do Home automation using NodeMCU and Blynk App. This is a simple but useful home automation project with Nodemcu and a relay module where we can control home appliances securely from the smartphone.
During the video, I have shared the circuit diagram, Arduino sketch, Blynk example library for this internet of things project.
For complete project details (schematics + source code) visit ► https://easyelectronicsproject.com/esp32projects/homeautomationnodemcublynkrelay1/
Download the Code: https://drive.google.com/uc?export=download\u0026id=1MfAQiRGZLdEABn4UJAnlROmnKR825Ru
You have to install the Blynk library before uploading the sketch. I have shown all the details in the video.
Required components for this WiFi relay module:
1. NodeMCU board
2. Relay Module 5volt
3. 5 volt DC supply
In this video, I have shown step by step how to download and use the Blynk app for this smart house project. I have also shared NodeMCU pinout details, which help you to connect the 4channel or 6channel relay module with the esp8266 Nodemcu board.
After watching the complete video you can easily design this lowcost smart home device and control the relay module with wifi.
