Hi, i am new to this forum and in need of some help.
I am making a exoskeleton arm as a senior project, I am using emg sensors to send amplified and noise reduced signals to a arduino that will in real time send them to a stepper motor driver. I do not have the items for the project, I just want to know if they are possible to be used for the project.
I also have some problems with the code, I want it to work in real time but I have no clue off how to write that code, if anyone have any ideas or know a place where they might have codes, that would be very helpful.
below I list the circuits and materials that I will use, I have not decided for the motor but it will most certainly be a 4 wire stepper motor.
thank you for the help in advance!
