Hey Guys! I am trying to develop my first project but I am really stuck. I need to develop vibration patterns similar to LED patterns using Arduino Pro Mini (3.3v) but I am having problems on deciding what power source (small as poosible) I use. And to supply enough current from the arduino to the motors. Please guide me towards choosing a suitable transistor for each motor as well.
I plan on using 6 small DC motors and I need to be producing different patterns wherby all six run together, alternates run, only one runs. etc.
Motor ratings (each): 3v, 70mA (max)
battery rating (I plan on using this): 3.7v, 80mA
