The Birth of CircuitPython: A History of Microcontroller Programming
Before we dive into the nitty-gritty of CircuitPython, let’s take a quick trip down memory lane 🕰️. Understanding the evolution of microcontroller programming helps us appreciate just how revolutionary CircuitPython really is.
The Early Days: Assembly Language and C
In the beginning, programming microcontrollers was not for the faint of heart. It involved wrestling with low-level languages like assembly and C, which required a deep understanding of hardware architecture and memory management. While powerful, these languages were complex and time-consuming to work with.
The Rise of Interpreted Languages
As microcontrollers became more powerful, the demand for easier-to-use programming languages grew. Interpreted languages like BASIC and Forth emerged, offering a more beginner-friendly syntax and faster development cycles.
MicroPython Paves the Way
In 2013, Damien George introduced MicroPython, a lean and efficient implementation of Python 3 designed specifically for microcontrollers. This marked a turning point, bringing the power and readability of Python to the world of embedded systems.
CircuitPython: Building on a Solid Foundation
Inspired by MicroPython, Adafruit created CircuitPython, a fork of MicroPython with a focus on education and ease of use. CircuitPython takes MicroPython’s core principles and adds features like automatic device detection, a built-in file system, and a vast library of pre-written modules for interacting with sensors, displays, and other hardware.
CircuitPython: A Beginner-Friendly Microcontroller Programming Language
What makes CircuitPython so beginner-friendly? Let’s break it down:
1. Simplified Setup and Workflow:
- Plug and Play: Connect your CircuitPython-compatible board to your computer via USB, and it pops up as a storage device, just like a thumb drive. No need for separate software or drivers!
- Code Directly on the Device: Your CircuitPython board has a built-in text editor. Simply open the
code.pyfile on the device, start coding, save, and watch your code run instantly. - No Compiling: CircuitPython is an interpreted language, meaning it runs your code line by line without needing to compile it first. This makes for a much faster and more iterative development process.
2. Python-Based Syntax:
Python consistently ranks among the easiest programming languages to learn due to its clear and readable syntax. CircuitPython inherits this advantage, making it incredibly beginner-friendly.
3. Abundant Resources and Support:
- Adafruit Learn: Adafruit, the driving force behind CircuitPython, offers a wealth of tutorials, guides, and project ideas on their website.
- Vibrant Community: The CircuitPython community is known for its welcoming and supportive nature. You’ll find forums, Discord servers, and online communities where you can ask questions, share projects, and get help from experienced users.
CircuitPython for Beginners: Getting Started with Microcontrollers

The board will automatically install the firmware and restart.
4. Start Coding:
Open the code.py file on your CIRCUITPY drive using Mu Editor or your preferred text editor. Here’s a simple program to blink an LED:
import board
import digitalio
import time
led = digitalio.DigitalInOut(board.LED)
led.direction = digitalio.Direction.OUTPUT
while True:
led.value = True
time.sleep(0.5)
led.value = False
time.sleep(0.5)
Save the file, and watch the LED on your board blink! Congratulations, you’ve just written your first CircuitPython program!
