Creating a basic Word Cloud in Python
We've all seen word clouds, like in the sidebars of blogs, but let's see how we might create our own with a little bit of code!
Connecting an Analog Joystick to the Raspberry Pi
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
Creating a Flickering Candle Using an RGB LED on the Raspberry Pi
After getting PWM (pulse-width modulation) to work with an RGB LED last week, I was trying to think of what else I could do with an LED that demonstrated changes in color as well as intensity.
I’m not sure why – maybe it was because we lost power in our
How to Use Pulse Width Modulation (PWM) on an RGB LED and the Raspberry Pi
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
A Simon Game Clone for the Raspberry Pi
Let's recreate the Simon game of the 1980s using a Raspberry Pi and Sonic Pi!
Flash an LED on Your Raspberry Pi When You Get New Email
Let's learn how to flash an LED on the Raspberry Pi when someone sends us a new email.
Building a Morse Code Transmitter on a Raspberry Pi (version 2)
I created a morse code generator before based on entering a string at the console. Now I extended it to generate a message by clicking a button.
