Remote Roller Blind

Introduction This automatic roller blind system offers a simple and customizable solution for automated window shading. The system is designed to work with standard curtain fabrics, which can be sourced from retailers such as Amazon or local hardware stores. The size of the blind is flexible, and the mounting pins can be adjusted individually using a custom file that has been published for modification. The control system is powered by an Arduino Nano, which integrates an infrared (IR) receiver (VS1838B) and a real-time clock (RTC) module (DS3231). A 28BYJ-48 stepper motor with a ULN2003 driver board is used to roll the blind up and down. The system is operated via standard remote controls, such as a TV remote, allowing users to control the roller blind on demand. Components from AliExpress Stepper motor with driver: 28BYJ-48 + ULN2003 Arduino Nano: ATmega328P CH340 IR Receiver Module: VS1838B Real-Time Clock Module: DS3231 Ball Bearings: 608ZZ Bearings Flashing the Microcontroller To upload the program to the Arduino Nano, copy the code from the provided text file into an Arduino project in the Arduino IDE. Then, connect the board via USB and flash the microcontroller. If necessary, the line Edit int receiver = 2; can be modified depending on which pin the IR receiver is connected to. The code also allows customization of: The time when the blind moves up or down. The IR signal that triggers each action. A helpful way to understand or modify the code is to copy it into ChatGPT and describe the desired change. This method works quite reliably and can assist with debugging or customization.
