Hi all.
I have to control 4 servo motor, simultanously.
The motors has to move in different speeds each one.
So, I don't know what would be the best strategy for deal with it... since the different speeds implies in different 'delay' values... but at the same time all the motors has to move together.
Any idea?
I've started an software to do serial communication (send position, what motor, etc) and the Arduino would be in charge only with the most basic job (evalutate the data and turn the motor). But I've realized that: if I have to send a single bunch of data to do a movement... I can't move several motors simultanously... or, maybe, I have to send a chain of data but each chunk should be so small (to make everything works like simultanously) that the overal speed (prepare data, send via USB cable, be interpreted, etc) probably would be too slow (and so my project ruined).
I thought using an single Arduino for each motor would be a better idea... but... 4 USB ports... 4 Arduinos, syncronize everything, etc... doesn't seem to be a good idea.
Thanks!
