Description

Micro:bit is significantly applied to STEM education for teenagers, as a small microcontroller, which features small in size, easy to carry, and powerful function. At present, innovative technology products, like robots, wearable devices and interactive electronic games can be produced by programming and code.
In this kit, we will guide you how to control and generate a Micro:bit turtle smart car through programming in Makecode.
MakeCode is a framework for creating interactive and engaging programming experiences for those new to the world of programming. The platform provides the foundation for a tailored coding experience to create and run user programs on actual hardware or in a simulated target.
To make you deeply know the micro:bit, we provide test code and projects.
The Keyestudio micro:bit smart car integrates obstacle avoidance, line tracking and IR and Bluetooth control functions. It contains passive buzzer, ultrasonic sensor, KEYES-2812-18R module, IR obstacle avoidance sensor and so on.
The passive buzzer makes music play, a KEYES-2812-18R module can display different effects, a photoresistor can detect light intensity.
Simultaneously, this smart car is chargeable. You only connect power to the port of battery holder.

Hardware:

The details of micro:bit board: https://tech.microbit.org/hardware/


Micro:bit Pins

Before getting started with the following projects, firstly need to figure out each pin of micro:bit main board.

The BBC micro:bit has 25 external connections on the edge connector of the board, which we refer to as“pins”. The edge connector is the gray area on the right side of the figure below. There are five large pins, that are also connected to holes in the board labeled: 0, 1, 2, 3V, and GND. And along the same edge, there are 20 small pins that you can use when plugging the BBC micro:bit into an edge connector.

Please refer to the following diagram shown below.

More details you could refer to the official website:https://microbit.org/guide/hardware/pins/


Install Drive of Micro:bit Board

1)First of all, connect the micro:bit to your computer using a USB cable.

And enter website https://fs.keyestudio.com/KS0426Driver to download the driver file of micro:bit, double-click thumb

thumb

After downloading the driver, then click “Next”

Code and Programming

We take Windows system as example to show you.

Get started with Micro:bit: Https://microbit.org/guide/quick/


Step 1: Connect Micro:bit Board

Link micro:bit board to computer with USB cable.(Guide to mobile apps:https://microbit.org/get-started/user-guide/mobile/) Macs ,PCs, Chromebooks and Linux system(including Raspberry Pi)support micro:bit.


thumb

There will be a MICROBIT drive in your computer, as shown below:


thumb


Step 2: Programming

We recommend you to use Google Chrome
Enter https://makecode.microbit.org/ then click thumb and you will view the dialog box.
Input“heartbeat”to name your project and click “Create”


thumb


thumb

Through MakeCode editor, you just need to drag blocks into code editing area to design program. There is a video to show you how to finish“heartbeat”pattern.
microbit-heartbeat.mp4
Next, we will introduce Makecode.


thumb

Step 3: Download Code

Enter Makecode editor, tap“Download”to get a“hex”file. Then copy it into MICROBIT drive.


thumb

thumb

Get “hex” file firstly, drag or copy it in MICROBIT drive. Then hex file will be copied on MICROBIT drive.


thumb


After the hex file is copied, the indicator of micro:bit board will be always on.

Step 4: Run program

Upload code on micro:bit board and plug in power with USB cable.
5 x 5 LED dot matrix will display heartbeat pattern.
