The presented project is of great use for owners of dogs and cats who, many times, need to travel and have no one to leave them with. Its operation is based on the LDR sensor. Every time a beam of light hits K1 it will be activated, which will cause two timers to start. The first timer will activate a valve (solenoid with spring return of one-pole x two positions), which consequently will provide feed to the container. The second timer activates K3 which will cause a water pump to fill the container. The LDR must be positioned so that the circuit is activated at dawn, thus feeding the animal, filling the containers.
