Will the UNO have enough pins for my project?
I want to use my ramps 1.4 with it.
I used a shield from adafruit to control steppers they use only 2 pins (SDA & SCL) on the arduino to control up to 64 stepper ( if you stack them ).

That being said, i fried the shield with a NEM17 because it is limited to 1.2A so i won't recommend them, but that mean that it is possible, you just have to find the right shield OR build it

Also you have to check if RAMPS use the SDA or SCL pin
