HM-10 Bluetooth Module interfacing with Arduino nano. To use the Digital pins of the Arduino with HM-10 the following connection needs to establish.

Here you will learn how to use HC06 with Arduino and the same method will help to work with other microcontrollers and even boards. First, connect the module according to the given circuit diagram. Then understand first how the device works. It acts as a slave. Hc06 can connect with external devices just by power on with the use of the password.

Enable/Key pin is the only pin that makes the HC-05 unique than the others. It helps to change the device between data mode and command mode using an external signal. The HIGH logic state will transfer the device in command mode and …

To use HC-05 Bluetooth module in AT command mode, connect “Key” pin to High (VCC). Default Baud rate of HC-05 in command mode is 38400bps. Following are some AT command generally used to change setting of Bluetooth module.

Apr 28, 2011 · It has 14 digital input/output pins (of which 6 can be used as PWM outputs and one can be used to reset the WT11 module), 6 analog inputs, a 16 MHz crystal oscillator, screw terminals for power, an ICSP header, and a reset button.

Jul 8, 2018 · Arduino Pins Bluetooth Pins. RX (Pin 0) ———-> TX. TX (Pin 1) ———-> RX. 5V ———-> VCC. GND ———-> GND. Connect a LED negative to GND of arduino and positive to pin 13 with a resistance valued between 220Ω – 1KΩ. And your done with the circuit. How Does it …

Note : Default Bluetooth name of the device is “HC-05” and default PIN (password) for connection is either “0000” or “1234”. Here, we will transmit data from Smartphone via Bluetooth to the Arduino Uno and display it on Serial Monitor of PC.

Learn how to use the Arduino BT with detailed documentation, including pinouts, usage guides, and example projects. Perfect for students, hobbyists, and developers integrating the Arduino BT into their circuits.

Each of the 14 digital pins on the BT can be used as an input or output, using [pinMode()](//www.arduino.cc/en/Reference/PinMode), [digitalWrite()](//www.arduino.cc/en/Reference/DigitalWrite), and [digitalRead()](//www.arduino.cc/en/Reference/DigitalRead) functions. They operate at 5 volts.
