Automatic Curtain

This tutorial will teach you to make an automatic curtain using Bluetooth.

Components

1) Arduino UNO

2 ) L298N (if using geared or BO motors) or TB6612FNG (geared motors work best with this)

3) Motors

4) Clamps

5) HC-05

6) Jumpers and wire

7) Adapter to connect to the Arduino for power/battery

8) String

Step 1: Clamping

Attach the clamps at the ends of your pelmet box.

Step 2: Connections with L298N and HC-05

On the L298N/TB6612FNG:-

in1=3

in2=2

ena=5

in3=9

in4=10

enb=6

GND-gnd(on arduino and the negative terminal of the battery)

5v-Vin((if using battery for the whole setup) )

12v- Battery( if using one)

On the HC-05:-

RX-0

TX-1

VCC-5v(or 3.3v)

Gnd-gnd(on arduino)

(Connect stby on TB6612FNG to vcc)

Step 3: Final

Attach the motors to the clamps and connect the outpins of the L298N/TB6612FNG to the motors

Attach the one string from each motor to one curtain ring/end(other ring/end end should be fixed)

And upload the code to the arduino

Step 4: Connection with Mobile

EXPANDED TECHNICAL DETAILS

Remote Window Automation

This project provides a convenient, smartphone-controlled solution for opening and closing heavy window curtains or blinds.

  • High-Torque DC Drive: Uses a powerful geared DC motor or a high-torque continuous-rotation servo. The Arduino manages the movement via a L298N H-bridge to handle the mechanical load of the fabric.
  • Limit Detection Matrix: Includes two limit switches (Open/Closed) or a magnetic reed sensor to identify when the curtain has reached its end-point, preventing motor stall and mechanical damage.

Interaction

  • Bluetooth_Con App Integration: The user can precisely set the "Percentage" of the curtain opening via a virtual slider on the mobile app, with the Arduino translating this into a timed motor run.
