micro: bit vs Raspberry Pi vs Unihiker: Which is the Best for Kids learning Python?

Many parents and educators often ask: What's the best option for kids learning Python: micro:bit, Raspberry Pi, or Unihiker? This article takes a closer look at each of these devices, comparing them across key areas like Python support, ease of use, Python programming tools, pin design, and hardware projects. Our goal is to help you choose the most kid-friendly tool for a fun and effective Python learning experience.

1. MicroPython or Python Support

When parents decide to use hardware to teach their kids Python, the first step is to choose a piece of hardware that supports Python. Both Raspberry Pi and Unihiker support Python, while Micro:bit runs a special version of Python called MicroPython. MicroPython is a lightweight version of Python, and it has some limitations because it does not support certain standard Python libraries, which may prevent kids from experiencing the full capabilities of programming.

2. Fast and Easy to Start

Getting Started with Raspberry Pi: Essential Accessories and Raspberry OS Installation

To get started with the Raspberry Pi, you'll need a few important accessories. First, you'll want a Micro-HDMI-to-VGA adapter so you can connect your Raspberry Pi to a VGA monitor. You'll also need an inline power adapter to make sure your Raspberry Pi has power.

Next, you need to download and install the Raspberry Pi OS, which is the operating system that runs on the device. After that, download the Mu Python Editor. It’s a user-friendly tool that helps kids start coding in Python. With these items ready, your kids will be all set to explore and learn Python using the Raspberry Pi.

Only Two Steps to Start Learning Python with Unihiker

Step one: Connect to a Computer

Simply connect the Unihiker to a computer using a USB cable. This connection allows you to establish communication between Unihiker and your computer.

Step two: Start Kids' Learning Python

Once connected, you can immediately start your kids learning Python because Unihiker comes with a pre-configured operating system and software stack. Unihiker also provides a user-friendly interface where you can write and execute Python code.

3. Python Programming Tools

Choosing the right Python programming tools has a significant impact on kids learning Python. Intuitive and easy-to-use tools can help kids quickly grasp the fundamentals of programming while reducing frustration.

Mu Editor and Thonny: Text-Based Python Programming on Raspberry Pi

Raspberry Pi OS comes pre-loaded with Mu editor and Thonny which is a Python IDE.

Mu Editor is easy to use and perfect for kids. It supports standard Python,making it great for hardware projects. It gives instant error feedback and has built-in tutorials to help kids learn quickly.

Thonny IDE is designed for learning and has user-friendly debugging features. Kids can run code line by line and see variable values in real-time, which helps them understand programming better.

Challenges with Case Sensitivity in Mu Editor and Thonny IDE

Some parents have mentioned issues with Mu Editor and Thonny IDE, such as incorrect capital letters, which mean their kids are not getting the code to work and need parental help to debug.

Mind+ Editor: Block & Text-Based Python Programming on Unihiker

UNIHIKER supports two different programming methods: "Python Blocks" and "Python Code".

• Python Blocks: Mind+ (similar to Scratch 3.0) uses visual blocks to help kids write Python code. Instead of typing, kids can drag and connect blocks to create programs.
• Python Code: If your kids already have experience with Python, you can choose a programming platform that suits their habits, such as jupyter notebook, VSCode, Thonny, Mind+, and more.

4. Pin Header Vs Edge Connector

Raspberry Pi's Pin Header is a Little Challenge for Kids

Most models of the Raspberry Pi have a 40-pin header, as shown in the image below. Of the 40 pins, 26 are GPIO pins and the others are power or ground pins. For kids just starting to learn Python programming and electronics, the 40-pin header of the Raspberry Pi can be confusing, especially because each pin has a different function.

Unihiker's Edge Connector: Simplifying Learning for Kids

Instead of a traditional pin header, the Unihiker uses an edge connector similar to what you’ll find on a micro:bit development Board. The design simplifies hardware connections and allows easy attachment of sensors. Its clear layout helps kids understand components, boosting engagement while minimizing the risk of short circuits. It also features an exposed backside to allow kids to learn directly about sensors and circuitry and to minimize the board’s volume.

5. Kid-friendly Python on Hardware Projects

Traffic Lights Projects with Raspberry Pi

When parents come to teach kids about the traffic lights project for learning Python, they need to prepare the following essential project components.

• A Raspberry Pi 400-point breadboard
• 3 LEDs (Red, Yellow and Green)
• A button
• A buzzer
• Resistors
• Jumper cables
• A Raspberry Pi (any version, including the Raspberry Pi Zero) SD card and power supply
• or a Raspberry Pi Pico (any version – you may need to solder your own header pins) plus 4 additional M-M jumper wires.

Traffic Lights Projects with Unihiker

To teach kids about traffic lights using Unihiker and Python, parents only need to prepare a Unihiker and three images representing red, green, and yellow. With these materials, kids can easily explore traffic light concepts while learning Python.

• Three images featuring red, green, and yellow
• Unihiker
