This is an automatic general purpose grain dispenser. It could be used to dispense specific amounts of granural stuff such as pet food, coffee, sugar, fertilizer, sand or watever you'd like.
Update 13 Jun 2018:
Note: Currently having issues with the steady flow of the material from the container to the machine (I'm testing with pet food wich is irregularly shaped and gets stuck in the cointainer hole). Maybe adding a servo with an arm that makes a sweep when needed will assist the flow and solve the problem.
