Resources and Advice for Building CircuitPython Projects
The Real Python Podcast
How Todd Bot Got the Name Todd Bot
Todd bot is an online simulator for the Raspberry Pi Pico and other chips. You can use it to run Circuit Python on a virtual raspberry Pi Pico in your browser. It's, I kind of taught myself list comprehensions while using this, you know, because he wanted to make sure that all the things you can do in normal Python also work in Circuit Python.
Are you looking to advance your CircuitPython projects? Would you like a collection of resources and tools to help you along your path? This week on the show, Tod Kurt is here to discuss building projects with CircuitPython.
Tod has been working with embedded electronics for a long time and has been an active member of the Arduino community. He recently started to build projects using CircuitPython, and it has become his preferred prototype method.
He shares software resources, hardware tools, and advice about working with CircuitPython and embedded electronics. We discuss several of his music hardware projects and the libraries and modules that he uses for synthesis. He also shares a powerful online prototyping tool to plan your project before spending money or plugging in a soldering iron.
Course Spotlight: Python Basics: Reading and Writing Files
In this video course, you’ll learn how to move data back and forth between your Python programs and external software by reading and writing files. You’ll practice reading and writing data stored in the CSV file format, one of the most widely supported file formats for transferring tabular data.
