This is a spectrometer that uses
1 your phone as a light source:
2 color filters: (https://www.amazon.com/gp/product/B0771LTPFN/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1,)
3 and an an Ellegoo super kit IF YOU USE A WIRE NOT A SWITCH THE KIT HAS NO SWITCHES (https://www.amazon.com/gp/product/B01D8KOZF4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) parts actually used and code here (https://www.tinkercad.com/things/inKaZFWLrGx-spectromemter)
to create a great scientific instrument for home/lab use or for demonstration

the phone I used was a Samsung galaxy S10+ if your phone is larger than this you will need to re size the phone holder, if you don't have a way to do this with out messing up the screw holes here is a link to the tinker cad so you can mess with it yourself https://www.tinkercad.com/things/fbE1btmqDMZ-p
