Introduction

In the previous course, we learned how to use an Android phone to control the car through Bluetooth. Here, we will learn how to use an IOS device to control the car.

The makecode programming code in this lesson is the same as that in the Android phone control lesson. Let’s learn how to start using the IOS Micro bit app first.

About the app

The micro:bit app is the essential companion to the BBC micro:bit, the pocket sized programmable computer. The app provides online access to a choice of code editors for programming your micro:bit and, when your program is ready, the app beams it to the micro:bit via Bluetooth wireless. Easy-to-follow screens lead you through the process of pairing your iPad (or iPhone) to the micro:bit and then transferring your program code.

In this lesson we will use the GamePad function in the app Monitor and Control interface.

APP Download

Open the App store on your ipad/iPhone.
Search the micro:bit to download and install.
