Gesture-Controlled Bluetooth Speaker Using Arduino

The music industry has been completely transformed by Bluetooth technology. For music enthusiasts, Bluetooth has made life simple with speakers and headphones. Their compact size portability and long battery life have made them a center of attraction. Well, we hereby take Bluetooth speakers to the next level by integrating touchless operation.

The Bluetooth speaker allows users to change music by just swiping their hands over the Bluetooth speaker. Also, the speaker allows users to adjust the volume by just raising and lowering their hand over the speaker. The user can thus operate the complete speaker operation without even having to touch his/her phone or the speaker.

Benefits of  Gesture Controlled Bluetooth Speaker

  • High-quality audio with a strong bass
  •  Full Contactless Usage
  • To change to the next song, swipe your hand
  • Changing the volume by raising or lowering the hand
  • Battery life of more than 8 hours
  • Portable, lightweight, and compact device
  • Swiping hand to turn On the speaker
  • Automatic turn Off when not in use

Proposed Gesture Controlled Bluetooth Speaker

The gesture-based speaker advances the state-of-the-art of Bluetooth speakers. The system includes an Arduino, battery charging board, Lidar sensor, audio amplifier IC, Bluetooth module, and 6-watt speaker with subwoofer. To connect phones to the speaker for audio input, the system uses a Bluetooth module.

A second charging input connector and an AUX connection for audio input are also supported by the speaker. The amplifier IC boosts the audio signal after it has been received without losing any data. Now, the speaker module receives this signal and transforms it into high-quality audio.

The Bluetooth speaker has a Lidar sensor installed on top of it. The Arduino processes the sensor’s input before sending it to the controller, which can then change the song, adjust the level, or turn on the speaker. This makes contactless speaker operation possible.

Power for the entire device is provided by the battery pack. The battery charger and protection circuitry regulates battery power and discharge. Additionally, this circuitry has an internal logic system that automatically turns off the system after more than five minutes of inactivity to conserve power.
