Gesture Sensor

Function introduction

The sensor features advanced gesture detection, proximity detection and digital ambient light sensing. Gesture detection can accurately sense "up, down, left and right" and more complex movements.

NyBoard

Software setup

Petoi Desktop App

• You can use the Firmware Uploader within the Petoi Desktop App.

  

Arduino IDE

• You can use Arduino IDE to upload and modify the source code.

The code using this sensor has been integrated into the OpenCat project. Uncomment the line #define GESTURE in the OpenCat.ino, as shown in the figure below, and then use the Arduino IDE to upload the sketch to the robot main board, which can reproduce the example function of integrating the robot action.

Prepare the Arduino UNO development environment

With NyBoard V1_*, you can choose Arduino Uno.

Modify the code in the OpenCat.ino

Hardware setup

After uploading the sketch, connect to the NyBoard with wire, as shown in the following picture:

BiBoard

Software setup

Petoi Desktop App

• You can use the Firmware Uploader within the Petoi Desktop App. Please select the correct Product type, Borard version, and Serial port. The mode should be Standard, so press the Upgrade the Firmware button. for example, Bittle, BiBoard_V0_2, COM5 as follows:

  

  After uploading, open the serial monitor and use the serial command "XG" to switch to using the gesture sensor mode.

Arduino IDE

• You can use Arduino IDE to upload the sketch(OpenCatEsp32.ino). Use the latest OpenCatESP32 code to finish the setup. For example, to modify the code for Bittle as shown below:

  

  After uploading, open the serial monitor and use the serial command "XG" to switch to using the gesture sensor mode.

Hardware setup

For specific use, the end connected to the sensor can be fixed on the robot's head (included in Bittle's mouth or attached to the top of Nybble's head); of course, you can also use your creativity according to your needs.

Testing code

If you want to test a gesture sensor's function alone or learn more about its principles. You can upload the demo sketch(ModuleTests/testGesture) using the Arduino IDE.

Note:

Before uploading the demo sketch, you must first set up the development environment:

• NyBoard

• BiBoard

This testing sketch implements real-time printing of various directional gestures (up, down, left, and right) made by the user in front of the gesture sensor in the serial monitor.
