Ok so this is going to sound a little strange but I am looking to have a timed lighting system that can be activated from a central area, similar to a bowling alley, and I thought that a pi might work rather well. Basically lets say I have 32 different area's, all with a light that is to last for 90 minutes, and can be turned on or off remotely and once turned on only stays on exactly 90 minutes. Possibly with a 3 light system, green (go) yellow (5 min left) red or no light (person is done)(even a simple on and off will work fine). Now for these 32 different areas they would be sectioned off into 4 sections of 8, each of the 4 sections are in different parts of the building but each of the 32 needs to run the exact same way. I basically need thoughts on how to program it, how to build and maybe someone to tell me that there is a better way if this is not the route to take.
Well, if you did work at a bowling alley; or owned one; this would be my reply as an Electrician. If This is how a bowling alley is wired when they built them; all the parts and wires to run them go to one circuit already in place. The difference in "raspberry pi" doing it; or "raspberry pi2". As hardwire goes, there it is controlled by an analog controller; where all the timers, delays, numbers are already wired to switches under its control (and manual ones, of course, and all the motors and all the pin set machines); in a Bowling light system. Here, instead, would go "isolated" control circuits, each having one part of the (and lower voltage or different lights; and effects (like running a sign). It can be done very easily; all of everything is a crispy money machine; all brand new; all bright where it needs to be; all colorful; all dimmed when and where it should; and for any exact period; it becomes "new"; wired for exactly what has the "total control" of it all...the program running, easy....(Vegas signs are this on xxxxx.....)......I have found raspberry pi in so many homes; in so many "control" type things; I did not know it would do anything; but it will. The System must be designed within safety guidelines (Electrical) and (physical is electricity); and have the "system" in a "controlled product"; like a room or theatre. This commercialism is where the raspberry pi works so well; pi2.
Easily wired, and wireless; per area; it is a loaded question; who is making the bowling alley new again? Home Automation Companies have some "machines" they use as their branding, why not raspberry pi2 (they use one too; they just do not admit to it)? In the Electrical Contractor field, it is easy to wire; and install needs "controls". Operating System is OpenElec is the opensourced ability for "controlled products" and what each wire hooks up to is any of them (ports on network it is really good at; which is the newest typed system operation's), or commands of; including robots etc.... Theatre uses them. Effects uses them. You can too!
