In some forum, I found someone said that i have to use the modified metro libraries, but the author of this instructable use the library straight from the github page and i use the same library file. Any help will greatly appreciated, thankyou.

  • Hi Ms @jorodeo, I currently study about the consideration to build a good colorimeter. I really interested in your design and wanted to print the design to be able to learn from it, thus i need to know some additional information in which i couldn't find in the documentation, therefore i want to ask to you a few questions:1. May I know the thickness of the acrylic enclosure?2. How long the exact dimension of each board (sensor board, shields & led boards)?3. May I know the exact diameter for the cuvette's hole (a hole which directly receives a light from the led, and another hole for the color sensor receives the light intensity) and its consideration?another question will follow, Thank you so much for your great contribution.
