UPDATE: So I bought a 12v-5v DC/DC convertor and wired it up to a 12v power supply from an old broken Wii. I have the full 12v running to the DC/DC convertor and also split off to the motor via the breadboard. The 5v coming out of the DC/DC then got wired to a micro usb plug that I cut off of another cable and runs to the TinkerKit LCD Module (Arduino Leonardo) to power it. Everything is working great and I can power the whole system with one plug. No longer portable, but where would I take it anyway? Haha. Also, updated the LCD messages. When it's watered the LCD displays "Thx I'm Good" and when it's dry it displays "Feed me Seymour".
I'm having trouble getting the motor to spin fast enough to pump the water using just the 5v power from the Arduino (TinkerKit LCD Module - Leonardo Board). I added a 9v battery to the system just to run the motor, but it only lasted a day and still struggled to do the job. Any recommendations as to how best to power the motor? Do I need a whole 12v supply you think?
