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 goal is to use the HC-06 module for controlling Arduino via Bluetooth communication //sending text commands from the the HC-06 module, and also sending text from the Arduino back to the the ...

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 ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.

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.

Lauterbach extends the range of Arduino supported boards and devices. After the successful integration of the »Pro Portenta H7«, Trace32 now also supports the Arduino »Nano 33 BLE« and »Nano 33 BLE ...
