I am an art student working on my senior thesis project and need help with understanding what is possible. As i am new to ardunio world i feel lost in the endless amount of products available. I am working with professors who have some experience in programming and using electronics and motors in their work, but what i want to do is a new challenge and i am trying to figure out the logistics.
I have prototyped a tongue that moves by four pull cables and i want them to eventually be fully automated (PICS). FYI, this is just a quick mock up and the final will be made from different materials. Now i see that i can control up to two step motors with the Arduino motor shield and they are stackable so i could put two of the shields on the board, but is there a cheaper product that will allow me to run 4 stepper motors on one board? if not can i run each motor in different directions and independently with multiple stacked motor shields? I plan i making 4-5 tongues once i figure out the first one.
While i understand that it will be expensive, i am just trying to figure out the most cost effective solution before i spend $40 on two shields per tongue. I also dont have any step motors in mind as i dont know how much torque will be needed, any suggestions would be much appreciated.
