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, ...

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 ...

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.

However, additional components — a Wi-Fi shield and a Bluetooth module – are required. The R4 WiFi is already equipped with Wi-Fi communication, thanks to the onboard ESP32-S3 module, which ...

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 ...

Based on a Nordic Semiconductor 32-bit ARM system-on-chip that has built-in support for Bluetooth 4.0, the RFduino runs the same code as Arduino UNO and DUE boards, and it works with any type of ...

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 ...

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 ...

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.
