DIY Motorized WiFi Roller Blind – ESP8266 & Blynk
Introduction
This DIY project demonstrates how to create a motorized WiFi roller blind using the ESP8266 microcontroller and the Blynk IoT platform. The project allows users to control the blind remotely using a smartphone app. It is a cost-effective solution for automating blinds without the need for expensive commercial options.
Components Needed
- ESP8266 microcontroller
- Stepper motor
- Motor driver board
- WiFi module
- Roller blind mechanism
- Blynk app
Construction
The roller blind mechanism is first modified to fit the stepper motor and motor driver. The ESP8266 is then connected to the WiFi module and motor driver. Blynk is installed on a smartphone and connected to the ESP8266 via its unique key. The app is used to control the blinds by sending commands to the microcontroller over WiFi.
Code
The Arduino IDE is used to write and upload the code to the ESP8266 microcontroller. The code includes libraries for WiFi and Blynk integration, as well as functions for controlling the stepper motor. The motor moves the blind up or down based on the commands received from the Blynk app.
Conclusion
By following this DIY project, anyone can create a motorized WiFi roller blind system using readily available components. The use of the ESP8266 and Blynk makes remote control of the blind simple and convenient. This project provides a cost-effective alternative to expensive commercial automation options.
FAQs
1. Can I use a different microcontroller?
Yes, you can use a different microcontroller as long as it has WiFi capabilities and can interface with the stepper motor and motor driver board.
2. Can I control multiple blinds with this system?
Yes, you can control multiple blinds by using multiple ESP8266 modules and Blynk app instances. Each blind would require its own set of components.
3. How do I calibrate the blind’s open and closed positions?
Calibration can be done by adjusting the code to determine how many steps the motor needs to move to fully open or close the blind. This may require some trial and error.

elinde fazla varsa pcbway de yaprıtsığın kartdan almak isterim
Was anyone able to get this to run on battery/solar?
I like the concept 👍🏻 Personally I would have added a homing sensor as sooner or later there will be a power failure or user error. It will be in my project ToDo list 👍🏻
hi
as soon as i change rollertime
it disconnects from blynk and the roller just keeps going
maybe can we add are timer when to rise and lower the blind ?
Dos't come ready? Hmm 👍
where is the source code ???
I dowloaded stl files. there were 3 blind_gear files. But in the video there are 4 blind_gear. Can you upload largest blind gear's stl file
Muy lento
Hello thanx for the video
My stepper motor gets hot holding position
is there any way to get it to reduce hold current? or not hold at all
i want to use 18650 cells to power this but if it constantly uses current then the battery wont last a day
Nice project but I see a problem. Code does not know where the curtain is and if you click twice the same button (up or down) it will continue going in the same direction and will burn at least, the motor!!
Hey, so I had a crack of doing this a month ago. My design was to have my mounting bracket and motor within the mounting bracket. Therefore the motor sits within the blind tube. I made a shaft with an internal gear for it to rotate.
I found it never had enough torque to spin the blind because of the weight of the blind.
Looking at your build, it seems to pull up the blind quite easy. How heavy is your blind?
Is there any faster motor?
And Is there a way to do it using zigbee protocols?
I can't get the ESP8266 module to pick up Wi-Fi. congratulations excellent video
works great for small roller shade. BUT does not work for big roller shade. anyone else got the solution for big shade?
is there a store in EU where i can buy all parts at once? the plast and pcb components etc? like a complete bundle
I will do this thank u
mert abi çok güzel olmuş bende hemen deneyeceğim ama stl dosyalarını bulamadım abi 🙂
Merhaba Mert, ilk senem ve bilgisayar mühendisliği öğrencisiyim.Aklıma sen geldin ve sormak istiyorum.
Elimde bir proje var ve nasıl yapabileceğimi bilmiyorum.
Konu şu, Ardunio simulator kullanarak müziğe duyarlı led yapmam lazım, sound sensöre sahip olan bir simulator bulamadım, sound sensoru olan ve içine müzik import edebileceğim bir simulator biliyor musun ? Yada müzik import etmek yerine buzzer ile şarkı koyup ledleride ona göre ayarlayabilriim.
(Konu dışıdır)
Saygılarımla.
