#2 from an old computer
#3 remember to power this buck and adjust the potentiometer to get a 5V output, before you connect the Arduino!!!
#4 I use 2 pin tactile switch from an old printer, if you want to use a 4 pin switch, before you solder the wires on it, check the continuity with a multimeter, so that the pins are not connected when the switch is not pressed, one of them will be ground and one to the Arduino inputs.
#5 the stepper works well with a 12V it will work also with 24V, the buck will provide in both cases a 5V to the Arduino, choose a power supply yourself, more info below.
#6 The size of the text files and images necessary for this pump are about 2MB, so any SD card over this size if fine.
