## Introduction

App inventor 2 is a blocks-based programming tool, which help beginners to build fully functional app in Android device. The interface is graphical base and support drag and drop operations. It consists of different components, such as button, slider, date pickers, image, camera, sensors including Accelerometer and connectivity to web, etc. The app can be exported or published to Play store for our daily life.<BR><P>

For creating IoT application, you can use App Inventor 2 to create web connection with micro:bit. In WAN control, after micro:bit is connected to internet, it keep listening and execute customized operation when WAN command is received. The customized operation could be Pin On/off, such as “open/close LED”, or set value such as “set the light intensity” and “set current time”.<BR><P>
