Python is everywhere. Its capabilities continue to grow. Not only can you create simple scripts, but you can create full-blown applications with it. The core has been scaled down to run on 32-bit microcontrollers like the ESP32 and Adafruit Feather M0. You can even use Python engineer modules to design stuff like circuits. There are electronics Python modules that create schematics, simulate circuits, and make solving math a cinch. Here are some of the modules I found that make Python usable for (electronics) engineering.
Up front, make sure you have a functioning Python environment. Update the package manager “pip” since all of these electronics python modules rely on it. Speaking of dependences, you may need to also install third-party libraries for some of them. From what I can tell, these all should be platform independent. However, I only tested these electronic modules with 64-bit Windows.

Back in 2013, a Kickstarter ran for a project to put a python interpreter on a microcontroller. At the time I could not see the benefit. Cool project, but I asked myself: “why?” On my last Adafruit order, I received a free Circuit Playground Express. The board comes with CircuitPython pre-installed. After playing with Circuit Python, or CP, I finally “get it.”
For Valentine’s Day, I made an animated LED heart for a new love in my life, Circuit Python. Well, love is a bit of a strong word. The past couple of weeks I have been learning Circuit Python, and I am excited by what it offers.
What is Circuit Python?
It is a Python implementation that runs on microcontrollers. The code exists on the microcontroller as text. The interpreter runs the code from that text file. Circuit Python is built on, or based on, MicroPython. Adafruit is designing it to teach programming. It is easy to get started, just open up the code.py file from the auto-mounted drive and start typing. When you hit save, the code runs. That’s it.
