What is it?

Introducing the Accelerometer-based gesture control module, a powerful device designed to bring intuitive gesture recognition capabilities to your projects. This compact module combines the ADXL345 accelerometer with an onboard microcontroller to accurately recognize and interpret a wide range of gestures, revolutionizing the way users interact with their creations. (See video below).

With advanced sensing capabilities, this module automatically handles gesture recognition for the accelerometer output, eliminating the need for tedious code writing. Simply connect the VCC and GND pins, as the module features an onboard 3.3V voltage regulator and operates on 3.3V logic.

The onboard microcontroller is specifically designed to analyze and interpret data from the accelerometer, allowing it to identify gestures with precision. However, it's important to note that this microcontroller is not user-programmable and is solely dedicated to processing the accelerometer output.

To fully utilize the gesture control module, it must be paired with an external microcontroller or Arduino. By connecting the module to an external controller, you gain the ability to customize actions and responses based on the recognized gestures. This integration enables you to create personalized projects that leverage the module's gesture recognition capabilities.

The gesture control module recognizes a variety of gestures, including forward, backward, left, right, activity, inactivity, tap, double tap, freefall, and shake. Each gesture corresponds to a specific interrupt pin (INT) that briefly pulls down when detected.

By configuring interrupts in your code, you can specify the actions to be triggered when the module detects particular gestures. This opens up a world of possibilities, allowing you to develop gesture-controlled robots, remote-controlled vehicles, and immersive gaming experiences.

The following gestures are recognized:

• Forward (INT 1)
• Backward (INT 2)
• Left (INT 3)
• Right (INT 4)
• Activity (INT 5)
• Inactivity (INT 6)
• Tap (INT 7)
• Double Tap (INT 8)
• Freefall (INT 9)
• Shake (INT 10)

By pairing this gesture control module with a microcontroller or Arduino, you can configure interrupts in your code to trigger specific actions when the module detects particular gestures. This functionality unlocks a world of potential, allowing for the development of gesture-controlled robots, remote-controlled vehicles, and captivating interactive gaming experiences.
