Automatic Pet Food and Water Dispenser with Display
so basically i just had this random idea of making a food dispenser for my dog since i had extra wires and components leftover from previous projects.
The circuit consists of:
Two containers, one for food and one for water.
Two servo motors each connected to open/close the food and water containers.
UDS to detect if the pet is near the feeding area.
FSRs placed in the bowls to detect if food or water is present.
LEDs to show whether each container is full or empty.
LCD to show the status of each container (full, empty, or neither).
Functionalities
- When the ultrasonic sensor detects the pet is near, the system checks if the food and water bowls are already filled.
- If the bowls are not full, the corresponding servo motor opens the container to dispense food or water.
- The force sensors verify whether the bowls already contain enough food or water.
- If a bowl is full, the system prevents dispensing.
- The LEDs indicate the current status:
- Green for full
- Red for empty
- Yellow for neither full nor empty
- The display shows textual information about the status of each container (full, empty, or neither).

OK.
That’s a great idea! I really like how you’re combining multiple sensors and actuators to make it smart and responsive.
From what you described, the logic sounds clear — using the ultrasonic sensor for detection, FSRs for bowl status, and servos for dispensing.
now do u start this project
what do u want from us?
