Pet feeders are automated machines that dispense food at preset schedule. They are mainly timed based and dispense a certain amount of food at specific time of the day. The pet feeder is a programmable system which is mainly controlled by a microcontroller. It consists of a LCD screen for input display, buzzer to alert pets for meals, stepper motor to control the speed and a turn table which is divided into different sections for placement of different food. User will be able to select the food to be dispensed out at their desired timing.
