What would I need to be able to use 5 Flex sensors and 5 stepper motors? I have the arduino uno. Do I need a mega? Thank you.
Note that each stepper driver would require several Arduino pins so the total pin count will be quite high.
Couldn't you just use servos instead of steppers, it would remove the need of external chips. Unless you are making a super-strong robot that can lift 50kg on its little finger!!
