Matrix module for SMARS, with this module it can now express some emotions and give you extra feedbacks!
You will need the following extra materials:
black transparent Polycarbonate (for "matrix_2" or you can try to print it with a translucent filament)
cnc 3018 (I used this machine to cut the polycarbonate and I'll do some projects based on this machine in the future)
For more informations about the code and how the matrix works, you can have a look at the following links:
