This project will be completed soon, and the goal is building an automatic and without human control vacuum cleaner.

The basic idea is to assemble a common little vacuum cleaner or an electric broom with an artificial intelligence structure and some motors.

The artificial intelligence will be performed with some PIC micros.

It is a little circuit PIC16F876A based, that with a relay and some little commands is able to give water automatically to your home plants and flowers. You only have to connect with a little pump, like those used in nativity scenes, select the time interval (every three or five days) and the time to let running the pump.

A question taken by some hobbysts is: how to make working a PIC 16LFxxx with low voltage? The datasheet say that it accept a supply range from 2.0V to 5.5V, but many users note that with a crystal of 4MHz the PIC starts running only up to 4V.
