Automated-Pet-Feeder

An automated pet feeder developed using TI's TM123GH6PM Tiva board. The system dispenses pet food at scheduled times and water based on owner's settings. Additionally, the feeder can detect motion for dispensing water, if set to "Motion" detection mode.

Features

• Scheduled Feeding: Set up specific feeding times for your pet.
• Water Regulation Option: Dispense water based on low water or motion detection.
• Alert Mode Option: Alert the owner if the water source is low.

Software Features

• time HH:MM: This command lets the user set the time for the pet feeder.
• time: Displays the current time.
• feed x y z a b: Adds a feeding schedule. Command contains 5 parameters - index, Motor duration, Motor Speed, Hours and Minutes.
• feed x delete: Lets the user delete a feeding schedule by specifying the index of the schedule.
• schedule: Displays the entire stored feeding schedule.
• water x: Sets the water level regulation by specifying the amount of volume. If water level goes below the level, water is dispensed if FILL mode is selected.
• fill y: Lets the user to choose between AUTO water filling or MOTION detected water filling.
• alert ON|OFF: If alert mode is ON, the user is alarmed when there is low water.
• setting: Displays the configuration settings - Water Level, Fill Mode and Alert Mode.

Interface

User can use a serial interface (Putty) to input feeding schedules and change other settings
