Generating Morse Code on the Raspberry Pi Using a Button on a Breadboard I created a morse code generator before based on entering a string at the console. Now I extended it to generate a message with a button click.
Using PullUp and PullDown Resistors on the Raspberry 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.
Building a Morse Code Transmitter on a Raspberry Pi I had made the Raspberry Pi blink an LED a few times, and as thrilling as that had been ;) I wanted to try something different. So I built a morse code transmitter!
Hello World for the Raspberry Pi (Making an LED Blink) I finally unboxed my Pi a few weeks ago, and since then I’ve been learning some Python, which is the primary language of the Pi. A whole new world opens up when you start experimenting with the GPIO pins, which let you interact with other devices and react to the surrounding environment.
Building a model 4-stroke combustion engine from Smithsonian Last summer, I found this “Smithsonian Motor-Works” set at a garage sale. Once built, it models a 4-stroke internal combustion engine. I’d shelved it for a rainy day and rediscovered it last weekend while cleaning the basement. The girls were out - time for a little father/son bonding!
