v21:
updated to ionic 4
added compare button with real data from internet
v13:
automatically asked for camera permission
to be used with a 3D printed attachment see screenshots
position attachment in front of the back camera
take a photo of the light spectrum from sunlight and click the ruler to analyze the emission spectrum
a comparison of the camera data and Wikipedia theoretical image
take a photo of the light spectrum from a normal lamp and click the ruler to analyze the emission spectrum
v6:
Physical Apparatus needed to use App
A diffraction grating to be placed in front of the camera
A light source such as a multi propose laser pointer
Handphone with App/Chrome Browser or a laptop with a camera
recorded to work better now
added back camera
added calibration of known zeroth and first-order diffraction light of the RED laser.
added auto find light
current version 4
some phones/Android OS (XiaoMi etc) may require App permission for CAMERA to be turn on.
some phones/Android OS (Samsung) could be automatic.
close the App and restart App again, it should now detect the given CAMERA permission.

Introduction
prototype
Interesting Fact
This data logger record intensity of brightness of red, green,blue light and even allows the phone camera to record real time data.

PITA to use. Does not show what area of the screen its using to calculate spectra. Will not back out of program. Kind of neat when you actually capture something, but very inaccurate since it doesn't show you where it's measuring from. While it does function a lot of work needs to be put into usability and the UI.
I had a diffraction grating, laser, and light ready, however inside the app there was no camera preview and no instructions. I tried pressing the camera button and nothing happened. I also tried checking and pressing pretty much everything and never really got it to do anything. If this app works it really needs help with the UI.
The idea is there. unfortunately, cellphone camera has an IR filter that rendered the measurement useless. may be a kit or diy box with a modified webcam + grating filter connected thru OTG might help. Florencent light as calibration base is accurate, simple and cheap way.
