Plenty possible. What sort of "power outlet" is it, and what might be connected to it?
The switching circuitry for the 110V would need to be sized for whatever maximum load needs to be switched. If it's just 10W, then a small relay or a solid state switch could do the job. If the intent includes switching large and inductive loads like motors, then that needs to be known and designed for accordingly.The way I read the description, the three stations are completely independent of each other. So while the three could be implemented with a single controller, each could be a standalone device with its own controller. The smallest microcontrollers (e.g. ATtiny85, less than $2 each) could be used in the latter case. I might favor three standalone devices, as it would reduce wiring and be simple to add additional stations if needed. But I don't understand the total scenario here, the purpose of the project.
I was a little vague.
Say I have a long table with three stations, each has a 10w power adapter coming from it. Red light on when power is off, green light on when power is on, yellow light on when 1/2 time remains.The "button" is really a computer input. Could I send a "yes" to station 1 and have it turn on while 2 and 3 remain. Or even better, have the computer handle the timing.
The lights simply indicate the availability of current, "in-use." Is there a way to get a "server" to send the "on" signal to stations independently of each other.
I don't see why not, depending on the computer and assuming appropriate interfaces are available.
