Light Analyzer (need Diffraction Grating)

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.

Acknowledgement
My sincere gratitude for the tireless contributions of Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, Félix Jesús Garcia Clemente, Anne Cox, Andrew Duffy, Todd Timberlake and many more in the Open Source Physics community. I have designed much of the above based on their ideas and insights.
