I am still thinking how I am going to build a fish feeder. I have looked at as many as I can and they wont do for me. I am not a builder so this part is not going to be easy (unless one of you guys fancy helping me in this bit).
What my spec is:
- It has to hold enough food for at least 4 weeks for at least two, possibly three, tanks full of fish.
- It has to be guaranteed to work.
- It has to receive a signal from an arduino (probably via the PWM method) that will pass a number which will equate to an amount of food. I.E. If the design is an auger and a motor it would be sent, say, "4.5" which would equate to 4.5 seconds for the auger to turn.
- It has to pass the fish food into a water tank, via gravity or perhaps another (?) method.
Ideas would be very welcome, thanks.
