A FT-232 USB to serial board is used to program the Arduino. A standard Bluetooth module has to have HID firmware installed. [Dastardly] makes a homemade daughterboard–er, ...

The Bluetooth module wants 3.3v logic levels so that is taken into account. The image above shows a buffer chip doing the conversion, but the Fritzing schematic on the post uses a voltage divider.

You know, we don't see too many didgeridoos in these parts (and for good reason, seeing as how it is little more than a pipe) but wait'll to you get a load of this aerophone-wielding maniac: Kyle ...

The Arduino, Bluetooth module (check your specs, some HC-05, and HC-06 may come on a breakout board expecting 5V), and USB Host shield all run off of 3.3V, but devices you want to plug into the ...

Once paired, these modules relay serial information from your smart device to the dev board and vice versa. Just reverse the receive (Rx) and transmit (Tx) lines between your Arduino and Bluetooth ...

Arduino is the first widespread Open-Source hardware project and, since 2005, has become almost ubiquitous in microcontroller projects. The Arduino Pro line is aimed at the more professional user who ...

Arduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module consumption is 286mA (Wi-Fi Tx 802.11n HT20 16.5dBm 100% duty-cycle) or 220mA ...

Check out the video below to learn more about the Bluetooth THINGY module. “We have all said it a 100 times, if we only had an App to tell us if our garage door is open late at night.

DastardlyLabs uses a USB host shield, a Bluetooth module, an Arduino Pro Mini, and a bunch of other random parts to create this little device.
