There’s a feature of every GitHub repo that in my experience doesn’t get a ton of love, and that’s the wiki. In all fairness, I’m not sure how much love it deserves - it’s sorely lacking in features. But did you know it’s a separate repo that you can clone and manipulate locally?
One of the best things about the Raspberry Pi is its GPIO pins. They’re just sitting there, waiting to be connected to all kinds of interesting peripherals so your Pi can interact with the world around it. We can send alerts, attach sensors, and even plug cards like the Sense HAT over top of the pins to do even more. A few months ago, I bought a set of 37 sensor modules. I knew they wouldn’t directly interface with the Pi, but that it was entirely possible to do it, so they were set aside for later. Well, it’s time to try one out, and I figure the mini-joystick might offer some interesting opportunities! ...
If you buy a kit with random LEDs, wires, switches, etc, you’re likely to end up with one or two of those funky little LEDs that appears to be white, and has 4 wires instead of 2. I had set mine aside and made a mental note to figure it out later – well, that time has come! The code in this article is available on GitHub, if you’d like to use it or just follow along. ...
After watching Scott Fradkin live-code Sonic Pi for an hour at a conference, it inspired me to make a little music of my own.
I was flipping through The MagPi back-issues and came across an article about setting up a virtual Raspberry Pi environment. It got me thinking… I’ve been playing around a lot on the Pi itself, but it’d be nice to experiment with code even when I don’t have access to a physical Pi.
When you start out creating circuits with the Raspberry Pi and its GPIO pins, there’s an unexpected but important concept to understand, called “floating”. To adjust for it, you need to understand how to use pullup and pulldown resistors.
I unboxed my Raspberry Pi a few weeks ago and started learning Python. Let’s code the “Hello World” of the Pi, and make an LED blink.
