Arduino Creative Project - Smart Curtain

This project shows how to use the two-stage transmission of the gear to drive the large gear through the small gear, so as to drive the curtain to move up and down.

Materials:

Crowduino Uno-SD V1.5 x 1

Crowtail- Motor Base Shield 2.0 x 1

Crowtail- Bluetooth Low Energy Module x 1

Stepper Motor x 1

4 Pin Crowtail Cable x 1

USB cable x 1

Next, start making smart curtains!

It is known that the higher the speed of the motor (gear), the smaller the torque.

According to this theory, we designed three gears of different sizes, which meshed with each other.

We also need to design a platform to fix the motor and three gears so that they can cooperate normally.

Install the stepper motor and three gears on both sides of the motor fixing platform, as shown in the figure.

After finishing the hardware part, let's start the software part!+

Open the arduino IDE, and design the program!

After writing the program, run the program to make sure the program is correct!

Place the whole intelligent curtain driving device on the wall and screw it on.

Download a Bluetooth serial port assistant on the mobile phone, and simply set the function keys.

After confirming that everything is ready, you can use your mobile phone for functional debugging!

Obviously, it works just fine!
