    still a budding electronics nerd world but here's some thoughts anyways:1) What's your motor rated for? Mine is rated 6V and has no problem running off the arduino's 5v and can even push water under a good amount of load. 2) Do you know the operating current? I've had some motors where I've given plenty voltage but if the current is too low, you'll get nothing. Arduino gives you 40mA and i dont know how much 9V batteries give you off the bat but I know it's not relatively much. 3) Those red and black wires coming from the back of your set up are from the arduino i assume? looks to me they're going through quite a bit of other components before reaching your motor. You might want to check the actual voltage and maybe current value reaching the motor cause there may be a significant drop....

    Very nice! I will be using this to keep my bonsai watered while im away from home. However, I was wondering if you could comment on the longevity of the hygrometer, as I plan on using this to maintain a plant over the span of 2-3 months and have heard most hygrometers dont like being kept in soil for prolonged periods.
