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.
