if there's one task that the Arduino platform lends itself well to is home automation, and the following example by Instructables user "drj113" demonstrates this. Based on a basic Arduino-type circuit his devices is an networkable remote programmable relay controller. That is, the user can control the sequence of operation for up to six LEDs from any another device on the network with a web browser. It was designed to run Christmas lights to display patterns however could find many other uses such as sprinkler controls, security lights, or even HVAC.
As you can see from the image above, the entire device is home made but quite professional. The creator used the toner-transfer method to make the PCB and it looks very well done. You can find all the required design files and construction tutorial from here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're making your own permanent Arduino-based project such as the relay board above - you'll need an ATmega328 preloaded with the Arduino bootloader:
This is the same Atmel AVR ATmega328P microcontroller used in the official Arduino Uno, as well as our Eleven, EtherTen, USBDroid, and other boards. Perfect for building your own Arduino-compatible project directly on a breadboard or on a custom PCB, or for replacing the MCU in an existing board. For more information to order, click here.
