Seeeduino Curtain Control

We often forget to pull up our curtain and just turn on fluorescent lamp if we have an automatic curtain, we can save the energy and contribute to the low carbon living.
The designed curtain has two modes: automatic mode and remote control mode.

1)Seeeduino V328 Brain accept information from sensors and give information to motor driver

2)small direct curent motor Move the curtain

3)L298 Dual H-Bridge Motor Driver Drive the motor

4)light sensing brick Detect the light intensity

5)Electronic Brick Shield V4 Expand interfaces of Seeeduino V328

6)IR Remote control transmitter Press the key and control the motor
7)IR Remote control reciever Receive signal from IR Remote control

Step 1 How to move the curtain?

First:The three signal inputs of the L298 Dual H-Bridge Motor Driver are EA, I1 and I2. EA is connected to the PWM interfaces to control the speed and I1, I2 are connected to digital interfaces on the Seeeduino V328 to set steering direction.
We connect EA to Seeeduino 's PWM interfaces and connect I1, I2 to Seeeduino 's digital interface.
So we can determinate the steering direction and the speed of motor.

Second:Here I have the motor mounted on a mechanical joint yard, the mechanical production of zygote is the first to find a gear, the gear can be driven up and down sliding access to justice. This is to control, or you can manually control.

The title is misleading as this is a blind not a curtain. However, nice tutorial.

Eh, the terms are fairly interchangeable to me, and, I suspect, many others.
