In order to demonstrate the Architecture for Control Networks protocol, David Stone has created a system based on a Freetronics EtherMega which has the memory space and onboard Ethernet to handle the task with ease. The ACN protocol is designed to send colour and intensity data to lighting equipment over a network, and with David's example system RGB LED strips are connected to the Ethermega and are used as output devices. The results are animated and quite fluid, for example:
If you're enjoying working with Arduino projects but find the Uno-sized boards somewhat constricting - it's time to move up to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
