LED matrices are a popular mean of displaying text, graphics, and animated information at gas stations, convenient stores, and many other public places. Raj’s new project is about making a Bluetooth-enabled 8×64 LED matrix display, where you can send the text messages through a smartphone over a Bluetooth connection. He used Arduino as the main controller and an HC-06 Bluetooth adapter to receive data from the smartphone. He has shared all of his design files and Arduino firmware on his blog.

TechBitar shared his latest project the BridgeDuino with boards from DirtyPCBs:

BridgeDuino is a Swiss army knife PCB for rapid networking of inexpensive wireless communication modules. Breadboards are super for one-off experiments. But after prototyping half a dozen wireless prototypes involving more than just two Arduinos, the wiring mistakes and associated debugging grew more time consuming.
I also wanted a PCB that can act as a shield to Arduino Uno as well as work with the inexpensive and low-power Arduino ProMini.

As of this release, BridgeDuino supports the following wireless technologies/modules:
IR Transmiter LED 940nm
IR Receive 38Khz
RF433Mhz Receiver
RF433Mhz FS1000A Transmitter
Bluetooth HC-06 & HC-05
Nrf24L01+

mcuoneclipse.com explains how to use the HC-06 Bluetooth Module. They write:

After my first post using a Bluetooth module, things have evolved a bit. The challenge with these Bluetooth modules is: they look the same, but having different firmware. I did not fully realize that until I have ordered another bluetooth module from dx.com: That module comes already on a carrier, so I assumed I can use the same driver as for my other module. I was wrong :-(.

HC-05 or HC-06

My earlier module which I received from another source (without an adapter, see this post) has a different firmware on it, known as HC-05, while my DX.com module has a HC-06 firmware. To be clear: the modules are the same, but the software/firmware on it is different, and the firmware uses the pins differently too

I came across this neat bluetooth module called HC-06. It can be found as cheap as $6 on ebay, and gives you convenient UART access to bluetooth wireless capabilities.

My 3yr old has this home-made LED clock in his room. I thought it was time for an upgrade since the clock was very minimalistic. Its only function was to keep track of time and display it on the LED panel. And considering it was my first “completed” project with avr (atmega168), I thought I could make it better this time around.
