Adjusting LED intensity based on ambient light

[bee_t]

Hello!

I have to do a project where i adjust the light intensity of a group of LED's based on ambient light, indoors. The light sensor I'll be using is a Vernier light sensor. I have no idea how to work with DAQ's (or what they are) or the sensor, I don't even know where to begin with this project. I've essentially been left to the wind by my teachers and I really need some help.

A DAQ is a device to messure electrical signals.

Your sensor will deliver a electrical signal which corresponds to the ambient light. (How the sensor encodes the info you can see in the Datasheets and manuals), you need to collec this signal with the DAQ and read it with LabVIEW, then do some math and calculate the LEDs intensity. Im a bit rusty in electronics, but I am guessing you have regulate the LEDs intensity witht he duty cycle of a digital signal which you need to generate with the DAQ.

I hope this can help you start!

Thank you!

You know a quick Google of "Vernier light sensor" lead me to their webpage and on there I found a link to this free book Hands-On Introduction to NI LabVIEW™ with Vernier.

I suggest you start there.
