Introduction: Automate Window Curtain Using Arduino
Links to the supplies: https://www.wedgehacker.com/automate-curtain/
Supplies
NEMA-17 Stepper Motor
Pulley Belt
L298N Dual H-Bridge Motor Driver
Single Relay
Arduino UNO
12v Power Adapter
Rocker Push Button
Female-to-Female Jumpers
Male-to-Male Jumpers
6mm Wall Plugs and Screws
Step 1: Mark and Drill the Holes for the Stepper Bracket
Step 2: Tie and Tape the Stepper Into the Bracket.
You can either just tape the bracket with the stepper together or you may use an actual stepper bracket.
Step 3: Fix the Mount Bracket to the Wall Just Below the Curtain Rope.
Step 4: Build the Circuit.
Since there are two methods to achieve this project, see the diagram.
Method 1: 1 Button, Push Open Push Close, though the Arduino starts with the code as the Window closed.
Method 2: 2 Buttons, one to Open and the other to Close.
Step 5: Download the Arduino IDE and Upload the Code to the Arduino
You can find the codes here: https://www.wedgehacker.com/automate-curtain/
To download the Arduino IDE: https://www.arduino.cc/en/software
Step 6: Test the Code
Check whether the Arduino rotates in the right direction, and listen out for noises as they may give a clue if one of the Stepper coils is inversed.
Step 7: Attaching the Belt to the Rope.
**See the video for a clearer demonstration.
