Projet Automatic cat feeder with scale

Dry food Rotary cylinder for stocking and dispense to the scale Scale

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

Electronic/Hardware/Software:

• Arduino with SDcard/RTC
• Serial to bluetooth module
