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?
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.
Step 2: Light Sensing Brick
And sometimes the sunshine can be dazzlingly bright. In this case we can use the IR remote control to close the curtain.
Step 3: IR Remote Control
Step 4: Wiring
Data output of light sensor is connected with analog pin2 of seeeduino(v328).
EA port of L298 Dual H-Bridge Motor Driver is connected with pin10 of seeeduino(v328).
I1 port of L298 Dual H-Bridge Motor Driver is connected with pin12 of seeeduino(v328).
I2 port of L298 Dual H-Bridge Motor Driver is connected with pin13 of seeeduino(v328).
