It is very useful to use an IDE to program your Magicbit with MicroPython firmware. Thonny IDE will be introduced to you in this session. Using MicroPython and the Thonny IDE, you’ll have your first LED blinking using Micropython and thonny IDE.
Upload Micropython firmware using Magicbit Uploader
If you are starting the programing, you should have uploaded the micropython firmware to the magicbit.
- Use the magicbit web uploader or download and install Magicbit uploader offline
- Connect Magicbit to the computer
- In the web uploader, press connect button and select the correct COM port. If you are using magicbit uploader offline, open Magicbit Uploader and select your device COM Port & press connect.
4. Install Micropython firmware
Installing Thonny IDE

- Download the version for Windows and wait a few seconds while it downloads.
- Run the .exe file.
- Follow the installation wizard to complete the installation process. You just need to click “Next”.
- After completing the installation, open Thonny IDE. A window as shown in the following figure should open.
Create First Project (LED Blink)
- Open Thonny IDE
- Copy – Paste following code on the editor
from machine import Pin import time led = Pin(16, Pin.OUT) for i in range(10): led.on() time.sleep_ms(500) led.off() time.sleep_ms(500)
- click save as and select ‘Micropython Device’ and choose file name as ‘boot.py’
- Click Run (Green Arrow) on the IDE — If the Green LED on the backside of the Magicbit is blinking, you have just begun the magic with Magicbit
