Oct 4, 2023 · BLE is not like normal HC05/06 modules, because it works on Bluetooth V4.0. To be able to connect to this module, your smartphone must have bluetooth version 4 or higher. Materials for Bluetooth Low Energy Arduino project. Arduino Uno; Bluetooth Module (AT-09 or HM-10) Breadboard, LED, and Resistors Kit; Smart Phone (with Bluetooth 4.0 or above.)How to Connect the Bluetooth HC-05 to the Arduino. 1) Connect the Arduino’s +5V and GND pins to the bus strips on the breadboard, as shown in the above circuit diagram. 2) Power the HC-05 module by connecting the 5V and GND pins to the bus strips on the breadboard. The HC-05 is powered using 5VDC but includes an on-board voltage regulator
Step 7: Testing. After soldering the components make sure you soldered all the terminals right using a multi-meter. After all the connections are done, you can now plug the programming shield on the Arduino, and connect the Bluetooth module to your computer, the default password is "1234".
