Generating Morse Code on the Raspberry Pi Using a Button on a Breadboard

Generating Morse Code on the Raspberry Pi Using a Button on a Breadboard

Last time, I created a morse code generator. It took user input from the console, translated it into morse code, and blinked an LED to “transmit” the message. I decided to build on that a bit, adding a button to the circuit that allows me to generate morse code from

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”. A Simple Circuit Imagine you’re creating a circuit using a breadboard. Something very simple… a button, some wire and a power source (like the

Building a Morse Code Transmitter on a Raspberry Pi

Last week, I made the Raspberry Pi blink an LED a few times. As thrilling as that was ;) I almost immediately wanted something more. Note: Source code for this project is available on GitHub. Goals Setup a simple circuit (LED and resistor) using a breadboard Learn about Morse Code in
