Coming back from PyCon 2013, I was looking for interesting Raspberry Pi project ideas that would attract the attention of both non-programming students and those with more experience. I was averaging one Raspberry Python class each month at my hackerspace, MakerBar.
I decided that the project should relate to Mother’s day and have something my students could take home or perhaps even give to their Mom as a nifty gift. I had a few new services in my mind including some cloud APIs like Stormcloud and Plivo which I ended up using for my Raspberry Pi project.
So I decided to teach my students how to access a web API and settled on the Call Mom button—a Raspberry Pi board with a set of four buttons connected via Plivo, which gives you not only the titular Call Mom button, but also a Call Dad button—just to be fair with Dads—a “Text Mom I love her” button, and a spare button which students could use however they want.
With this Raspberry Pi project, I had won Twitter contest sponsored by Plivo at PyCon and my students had a great time building their own buttons in class. Now let me share how I built Call Mom using Raspberry Pi and Plivo.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email firstname.lastname@example.org to let us know about your post so we can blog it up here.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
