Pay close attention to the steps below to get your HC-05 Bluetooth module ready for Arduino programming. Before we start with the first example, controlling an Arduino using a smartphone, let’s take a closer look at the HC-05 Bluetooth module. Name: HC-05; Password: 1234 (or 0000) Type: Slave; Mode: Data; Baud Rate: 9600 with 8 data bits, no parity and 1 stop bit; Circuit Diagram for Interfacing HC-05 Bluetooth Module with Arduino Arduino (RX) = HC 05 (TX) Arduino (5v) = HC 05 (Vcc) Arduino (GND) = HC 05 (GND) Arduino (RESET) = Capacitor (22nf) = HC 05 (STATE) Remember you need a voltage divider if your arduino is 5v rated since HC 05 TX & RX are 3. IO1: RX (Arduino TX, HC05 RX) Connect via 1K+2K potential divider. . 0 standard. The following is a list of few of the default settings of the HC-05 Bluetooth Module. HC05 module comes with a 2. 1. GND to GND on the Arduino. 3V and is not 5V tolerant. A Logic Level Converter is recommended to protect the sensor if connect it to a 5V device (e. 6VDC to 5VDC, however, the logic level of RXD pin is 3. To simplify our tutorial, we will not use the voltage divider rule but it is recommended to 3. Wiring First, wire up your module and Arduino board just like in the image below. 3V otherwise your Rx pin may be damaged. The potential divider is required on the RX pin to shift the Arduino 5V TX pin down to 3. Mode 1 berperan sebagai slave atau receiver data saja, mode 2 berperan sebagai master atau dapat bertindak sebagai transceiver. Connecting HC-05 with Arduino is straightforward, but there’s one important detail — HC-05’s RX pin works at 3. code for led bluetooth control. TXD to RX (Pin 0) on the Arduino (use a voltage divider for safety). If you need a divider then Resistor would be 10k and 15k and TX of Arduino would move to the joint of the For more information about HC-05 Bluetooth module and how to use it, refer the topic HC-05 Bluetooth module in the sensors and modules section. Note: Rx pin receives a 3. May 12, 2021 · The HC-05 Bluetooth Module will work with supply voltage of 3. To avoid damaging the module, we add a voltage divider between Arduino TX and HC-05 RX. Comparing it to the HC-06 module, which can only be set as a Slave, the HC-05 can be set as Master as well which enables making a communication between two separate Arduino Boards. Note : Default Bluetooth name of the device is “HC-05” and default PIN (password) for connection is Jul 3, 2021 · HC-05 Bluetooth Module. arduino bluetooth controller .

Arduino: HC-05: IO0: TX (Arduino RX, HC05 TX) Can be connected directly to the Arduino Uno as it will accept 3. #include <SoftwareSerial. 2 Project by MukeshArvindh. This is probably the simplest code to test all the device that support the serial port communication. I will show you how to connect your HC-05 module to an Arduino UNO in a few simple steps. Now we will configure the HC-05 with the help of AT command. Rather than linking the HC-05 Module directly to the Arduino’s hardware UART, we’ll utilize SoftwareSerial and connect the HC-05’s RX and TX pins to any available digital pins on the Arduino. You can use a male-to-female Dupont cable to connect HC-05 and the Arduino UNO. Connection Diagram of HC-05 with Arduino Interfacing HC-05 Bluetooth Module with Arduino UNO . HC-05 Bluetooth Module. Connecting the HC-05 Module to an Arduino is straightforward: apply power and wire up the serial RX and TX pins. */ 3 4 /*If you are going to copy and paste the code, then do not forget 5 to delete the void setup() and void loop() function from the 6 sketch you are using before doing so,as the functions already 7 exist in this sketch. c_cpp. Module Bluetooth HC-05 adalah module komunikasi nirkabel via bluetooth yang dimana beroperasi pada frekuensi 2. 3V required by the HC-05 RX pin. Project description. h> Mar 3, 2025 · How to Connect HC-05 with Arduino UNO. It simply connects the computer terminal and the HC-05 in a loop. To do that you can use the voltage divider rule.
