Wireless LED Sign – XBee + ioBridge

OharaRP created a wireless LED scrolling sign that displays messages received from the Internet. The sign uses an array of 8×8 LED modules connected together – expandable to 16 segments. The LED’s are controlled by a MAX7219 controller board that can receive messages from an Xbee wireless module and is power by 5VDC (using a standard mini-USB plug). The sign has a wireless base station that forwards text and commands towards the sign relayed from Twitter or an ioBridge widget embedded on a website.

In this photo OharaRP sent IOBridge to the sign from his iPhone.
