Hi i'm trying to use a keypad just like this with my project. what I want to do is press a key (say 1) and have that action run a user defined function (the function controls three servos). Any thoughts on how to make that code. I;m very new to programming and arduino.

this is probably a stupid question with an easy answer, but can you tell me how to "download and add the code to the library" ( 1:10 )

hello I'm new to arduino, it is possible with a 4x4 keyboard to drive 2 stepper motors, bearing in mind that one motor uses variable degrees and the other motor uses displacements in cm, congratulations for the video (I used google translator I hope it worked well)
