give your Arduino a 120 volt kick in the pants!
The Arduino is a great tool for anyone interested in learning microcontroller programming, but after blinking some LEDs, what's next? This project enables your Arduino to control real-world 120 Volt electrical appliances you have in your home.
what can you use a plugduino for?
Well, its great for Halloween prop controller to automate your lasers, fog machines, fans and such in an intelligent way. You can use beam breaks, contact pads, distance sensors, and so on to control up to 4 devices independently or in unison to make a unique experience.
But you can also use in the house to control appliances based on sensors such as temperature, humidity, motion, light, and so on to open curtains, turn on lights, fans based on environmental conditions. You can also use it for more whimsical things like sign marquees, animated Christmas light lights, super sized Simon game, and anything that takes input, runs program logic, and controls 120V devices.
plugduino is a smart relay controller
which means that you can write a program that determines how each of the four electrical outlets are turned on or off, and in addition supply up to 4 inputs into the logic to interface it to the outside world. As a simple example, you can make a sequencer for the lights with a speed control simply by connecting a potentiometer to one of the inputs and using its value to control the sequencing speed.
