Gesture control omnibit

1. Purpose

In this course, we mainly learn to use Micro:bit, gesture recognition module and Omni:bit to realize gesture choose music.

2.Programming method

Mode 1 online programming:

First, we need to connect the micro:bit to the computer by USB cable. The computer will pop up a USB flash drive and click on the URL in the USB flash drive: http://microbit.org/ to enter the programming interface. Add the Yahboom package: https://github.com/YahboomTechnology/GR and https://github.com/lzty634158/OmniBit to start programming.

Mode 2 offline programming:

We need to open the offline programming software. After the installation is complete, enter the programming interface, click [New Project]. Add Yahboom package: https://github.com/YahboomTechnology/GR and https://github.com/lzty634158/OmniBit you can start programming.

3.About wiring

4.Combine building blocks

We need to use the following programming building blocks.

Summary procedure as shown below.

Gesture recognition module needs to be initialized by initializing the recognition block. If the initialization is successful, it will return 0. If the recognition is fail, it will return 255, we can restart the program by pressing the reset button of the micro:bit.

Store the recognition result in the value variable, and compare the value of the value with the selection gesture as a building block. If the two are equal, it is the corresponding gesture.

5. Phenomenon

After the program is downloaded successfully, if the initialization is successful, the micro:bit dot matrix will be a smiling face, and if it fails, it will be a crying face.

You can press the micro:bit reset button to restart the program to initialize.

Open your palm to face the module.

Swing over your palm from left to right in front of the module, the car pan left and the dot matrix arrow points to the east.

Swing over your palm from right to left in front of the module, the car pan right and the dot matrix arrow points to the west.

Swing over your palm from bottom to top in front of the module, the car back and the dot matrix arrow points to the north.

Swing over your palm from top to bottom in front of the module, the car advance and the dot matrix arrow points to the south.

Make a fist and stretch out two or three fingers to point to the front of the module, then circle it clockwise for a while, car will spin right.

Make a fist and stretch out two or three fingers to point to the front of the module, then circle it counterclockwise for a while, car will spin left.

Approach from back to front directly in front of the module, the car will large angle drift.
