control venetian blind using DC motor

[hafiz]

hello everyone..im from malaysia

im want to know how to create VI which i could control DC motor..

the DC motor will control the venetian blind according to lux density..it will open angle by angle syncronize with the lux density and time 

for example..on normal weather(malaysia, without rainy)on the morning the blind will open 45* (*=degree)..on noon the blind will open approx less then 45* since heat penetriate from the sun..while on evening the blind should open max to get full illuminations..

could anyone help me on what function should be used or maybe some basic and moderate example of yours?

Hi,

Please do not create duplicate post (http://forums.ni.com/ni/board/message?board.id=240&message.id=8183).

You provided information on your project and what to be achieve in your project but you did not mention what hardware you are using. Eg, which DAQ card you are using, what software (ie. LabVIEW or others), etc.

Split your project objectives into smaller projects, like 1 for controlling DC motor, 1 for reading lux density. Make sure all these can be done individually before you merge them together into a single project.

What functions to use will depend on what software and hardware you are using.

Regards

Lee

 im using student edition labview 7.1 and niDAQ usb 6009 

1.i want to control a dc motor which react like stepper motor but moves smoothly 

2. the lux meter will collect data and sent it to dc motor 

 do i need to used PID controller?
