Could it be easier than this? Check out an automated window blind controller I built.

Hi, I'm @techlhab. It's of great delight to share with you one of my recent Embedded Systems projects which is the development of an automated window blind controller. The device can be wirelessly controlled either using an IR (Infrared) remote controller or via a mobile application developed to interface with the device by connecting the device and the app wirelessly with Bluetooth.

This project is developed as it solves a lot of problems, eases tasks, safe stress, and makes it easy to control window blinds automatically and in a simple and very smart way just with a press of a button either on the remote or mobile application.

Arduino is the microcontroller used in the project which is where the code is been uploaded to, then all other components attached to it send and receive instructions from it.

HC-05 is a wireless Bluetooth module that can act as both master and slave, it's the module that is responsible for the communication between the device and the mobile application developed.

The mobile application used to wirelessly interface and control the device through Bluetooth connection is developed using the MIT (Massachusetts Institute of Technology) App Inventor a web application integrated development environment owned by Google but now managed by the Massachusetts Institute of Technology.

Hardware Materials used include:

1. Arduino Uno
2. Stepper Motor and Motor Driver
3. IR Receiver
4. IR Remote Control (Transmitter)
5. HC-05 Bluetooth Module
6. Lipo Battery
7. TP4056
8. DC-DC Step-Up Converter
9. Control Switch
10. Indication LEDs

Software used includes:

1. Arduino IDE (Integrated Development Environment)
2. Embedded C/C++
3. MIT App Inventory Platform
