MB0102 Keyestudio Microbit Main Board +USB Cable+Battery Holder with Batteries

Description

Micro: bit is an ARM-based microcontroller designed by BBC. Consisting of onboard Bluetooth, accelerometer, electronic compass, three buttons, 5 x 5 LED dot matrix, it is only half the size of credit card and mainly used for programming education for teenagers.

And this basic starter kit which includes a micro: bit control board, 1m USB cable and a battery holder (2 AAA batteries included, wire length 160mm)is designed for you to easily use micro:bit.
(Please note that the USB cable is for uploading program to micro:bit and the 2 AAA battery holder is for power supply.)

Instructions for Programming

The Micro:bit programming environment includes both online programming tools and local programming tools.Here we want to introduce how to program via the Google browser.

First, log on the official website of makecode https://makecode.microbit.org/ to use the network module to start the graphical programming, as shown below:

Click “JavaScript” to find the corresponding code as shown below:

Name the program as”LED1” and click icon “” to save it;

You can see the corresponding file in the C drive, as shown below:

Connect the micro: bit main board to your computer with the USB cable. The computer will automatically recognize the installed driver, so no manual operation is required. Then find the file “microbit-LED1” in the C drive disk and send it to “MICROBIT(G)”. The code is uploaded.

When the Micro:bit main board is powered up, the 5*5 LED dot matrix on it display the pattern.
You can power it via USB cable or 2 AA 1.5V batteries.

Power via USB Cable
