If you are looking to use this module permanently in a product, I suggest using a bidirectional level shifter module available in the market. Above, you can see the assembled image of the PAJ7620 ...

A controller can be interfaced with the Bluetooth module through the UART protocol. The speech is received by the android app and processed by the voice module. Voice is then converted to text. [1] ...

The Arduino gets a Bluetooth attachment and a set of code. Then you'll need Android Meets Robots, an app that lets you pair voice recognition with any Bluetooth module.

In this research paper, a system is being proposed, which focuses on the concept of how a robot can be controlled by the human voice. Voice control robot is just a practical example of controlling ...

A power supply, e.g., 12V 500mA or 4 AA alkaline batteries (rechargeables: use 5).• Optional: An Arduino project box.• Optional: A proto shield to mount the real-time clock module.

The phone uses an app that talks to the Arduino via Bluetooth, which means the Arduino needs a Bluetooth module. The Arduino controls what amounts to an upside-down 3D printer.
