Case15 Use with Joystick

Introduction​

In this course, we will introduce how to use the Joystick:bit V2 remote control to remotely control the XGO Rider. Students will learn how to program the micro:bit wireless group and how to program the Joystick:bit V2. By combining these two innovative devices, you will be able to experience more fun and interactive ways to bring more functionality and action to the XGO Rider.

Teaching Objectives​

  • Learn how to use and program the Joystick V2 remote control.
  • Learn how to program the Joystick V2 to communicate with the XGO Rider.

Preparation​

Before starting the lesson, please make sure you have prepared the following necessary materials:

micro:bit V2 * 2
XGO-Rider
Joysticks V2
USB Cable
PC

These materials will provide you with a complete experience and ensure that you can follow through and learn smoothly. If you are ready for the above, we can move on to the next step.

The XGO Rider will need to be moved back and forth in small increments to keep it balanced when it is turned on, please do not place the XGO Rider on the edge of a table or in a dangerous place to avoid damage.

Teaching Process​

Introduction​

Both Joystick:bit V2 and XGO Rider use micro:bit as the main controller, and it is possible to communicate between the two main controllers based on the Bluetooth function of micro:bit V2. Therefore, this tutorial will program both devices using a graphical programming platform: MakeCode. Whether you are a beginner or a professional, with this tutorial you will be able to easily master the remote control of the XGO Rider and bring more creativity and inspiration to your research, teaching or entertainment projects. Let's get started!

Exploration Activities​

  • How is Joysticks V2 programmed?
  • How does Joysticks V2 communicate with the XGO Rider?
