The Arduino platform lends itself very well to many forms of automation, whether that be controlling relays or moving actuators and motors depending on a certain outcome. Another interesting example of this has been demsontrated by Savio Dimatteo who has created an automated liquid-pouring system.
Unlike other versins which use pumps and flow meters, Savio's version is clever in its' simplicity ... a straw is fitted to the bottom of the storage vessel, and attached to a servo. This servo can then bend the straw upon command and thus allow the liquid to flow (or not). This can then be controlled using a near user-interface with three buttons and an LCD. You can see it in action through the following video:
This could be fun for a school project, such as automated plant waterin or perhaps adjusted for other purposes. Either way, check out Savio's website to learn how. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.
If you're looking to learn how to use an Arduino with sensors, servos, LCDs and much more - you can't go past reading a copy of "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more.
