V2 NOIR camera
I screwed noir camera with led but it didn't work.
Does led need resistance or more power?
It does not work, because you are not powering it. Holes on camera module where you screwed it are not powered. You must wire it from RPi's 5V pin.

As the title says I'm looking to have my phillips hue hub recognize my raspberry pi as a hue light bulb. From there I want to read the input to change some led light strips I have attached to it.
The easiest way to do this is to add a regular hue light and let the raspberry poll the hue hub about the state of that light. Use these values to change the ledstrip. After that you don't have to use the original light bulb. The Hue app will mark it as unreachable, but it wil still update the state in the bridge.
When I searched about it on google and youtube I get this :

In the video the focus of the camera is set physically by rotating lens of the camera but the lens of the camera is very sensitive, is there any other way to set the focus of camera module either by code or physically?
Thanks in advance
Is it possible to turn off the HoloLens infrared sensors in my unity application? I am using another external infrared sensor and the HoloLens infrared lights are interfering with my other device.
That is a great question, and, so far, Microsoft has not exposed an API to turn the Infrared Lights off. From my experiments, those LEDs play two critical roles. First, they light the environment so that HoloLens can create a 3D mesh (Spatial Mapping) of the environment in a similar way to what Microsoft Kinect did in Kinect Fusion. Second, they might help with gesture recognition.
If you are not using Spatial Mapping, and most of your interaction will happen through other means then air-taps, you can safely cover those with tape. Luckily, those LEDs are not a crucial part of HoloLens' implementation of SLAM (Simultaneous Location and Mapping), so Holograms will stay anchored onto anywhere you pinned them.
I was wondering if there was a way on a raspberry pi to track people, and then communicate with GPIO pins to turn servos so something faces their direction. I know it is possible to track using simulink, but I am not sure how to act on results. Thanks for any responses!
I have a digital camera that doesn't support for taking a photo from the computer.
can I control this camera by matlab? or may I need a digital camera that supports it in order to control it by the matlab?
I just want to take a photo from matlab (there is a usb that is connected between the camera and the computer).
If you want to control cameras with Matlab you should have the Image Acquisition Toolbox. Additionally the camera you want to connect must be supported by the Toolbox.

In case your camera is also having A/V R output(like in Sony digital camera), you can use a USB TV Tuner for capturing the analog signal and then use matlab to capture the video/images in real time from camera. Works for me !!
