They See Me Scrollin'

(Volunteer) This project was a good way for me to get acquainted with using an Arduino. I purchased the components as well as assembled and soldered the LED Panel together. The scrolling screen works by pairing the bluetooth module to an Android phone, and sending commands via an app. The commands are then send from the bluetooth chip to the Arduino via the TX, RX pins. They are processed and sent back out 3 digital pins to the LED display. As per the guide, I have used three 10K Ohm pulldown resistors (grounded) between the digital pins and the LED panel to avoid garbage data being received by the panel. The final result is a nice, remotely controlled scrolling screen that can process messages in either Red, Orange, or Green. This project also allows for daisy-chaining multiple LED assemblies in the future to make an even longer display. This project was a lot of fun, and I had a great time at this year's HackSI! http://www.instructables.com/id/Arduino-SPI-7-Bi-color-LED-Matrix-Scrolling-Text-D/
