I am doing a design project for a class in which i plan to have a large transparent acrylic screen overlaid with Pixels of SmartFilm( Film which has varying states of opacity based on the voltage supplied) and i want each pixel/ row of pixels to change their transparency based on a given input either through Arduino or FireFly(Plugin to grasshopper).
So for a small prototype, i (not having any background in electronics) had some questions
1] As i want the Pixelized screen to have minimum visual interference of the wires connecting them, how can i determine the minimum size(gauge) of the wire i can use for each pixel ?
The pixels at the periphery of the frame can be wired ( along with the copper electrodes inside the frame ). Any suggestions regarding how to tackle the pixels in the center with minimum interference ?
How can i set up the circuit ? I know i will need additional components like Relays, transformers (as the smart film operates on 110V) etc ? How do i go about choosing them ?
How many Pixels would i be able to control with one Arduino board ?
Any suggestions regarding wiring the smart film ?
P.S - (Attaching a Diagram Below)
