Arduino Mega 9DOF Bluetooth Shield

This is an Arduino Mega 9DOF Bluetooth Shield.

On http://benshobbycorner.nl you can find a small movie how it is working.

Have fun

Whoa, that looks impressive. I'm impressed it (presumably) all worked first time!

A lot of expensive kit on that shield.

45 dollar for the sensors (Sparkfun), 12 euro for the Bluetooth module (www.tme.eu). Board made at www.pcbcart.com And yes first time all working. C is not my native language so I am struggling with bluetooth to get that part working. Arduino 9DOF AHRS code from Sparkfun is working however.

That's not too expensive. Bravo on it. It looks great!

I can imagine the bluetooth code would be tricky but I have never used bluetooth with an arduino.

Code is on my weblog at this moment… :wink:

We had to put some delay between the characters to get it working.

When the bluetooth module is programmed it takes a few seconds to pair…

Bluetooth working on the Arduino Mega 9DOF Bluetooth Shield. Had to put the BTM-112 in slave mode, and had it communicate on 57600 baud. Wrote a small program to put it as slave (ATR1), and with a ATL4 you put it on 57600 baud. And while I was busy with an ATN= I have changed it's name. After that you have to cycle the Arduino Mega power and the new settings are working. On your PC or Laptop do a discovery of Bluetooth devices and you will find your Arduino Mega 9DOF Bluetooth. If you have not changed the PIN-code, with a 1234 your will get a connection. An invisable wire? We bought the module at http://www.tme.eu , before they had only a class 1 and a class 2 module, but after a check today we have seen there are a lot of new modules. In the 9DOF AHRS Arduino software change all Serial.print into Serial1.print, make the bluetooth connection to your PC or Laptop, change the Python (IMU_Razor9DOF.py) lines to get the right COM-port on 57600 baud and of you go? Will make a new movie tomorrow?

Just reading your blog! Good stuff. Long time microcontroller user :)

Display working on the Arduino Mega 9DOF Bluetooth. A Nokia 6100 (Epson). 132 x 132 pixels. Had to make a small DC-DC step-up converter to make 9.5 volts for the backlight from the Arduino 5 volt.
