This automatic cat feeder have to precisely weigh the food (1 gram precision).

Brainstorming:

• a turning cylinder with a trap for filing and a hole for emptying.
• a bowl fixed to a scale with a servomotor receive the food.
• when the desired weight is reached, the bowl is poured to a dish.
• Battery and wall-plug powered.(In case of power breakdown)
• Detect when the food level is low in the cylinder (IR barrier)

Preliminary:

• find a scale who can be easily read by an arduino
• find the size of the hole in the cylinder
