The wiring for this project couldn’t be simpler. Most starter electronics kits come with all the pieces we’ve listed above, so if you have a kit, take a look through what you already have when starting this project. Keep that in mind going forward.Īs for the physical components, here’s what you’ll need: Arduino Uno It’s not very complex code, but you’ll need to understand how arrays and switch cases work. However, if you’re brand new to coding, you might want to take this project in chunks. You won’t need much to make this project work in terms of hardware. Notably, with very little modification, this same method could be used to convey the message through an LED, since both devices can be rapidly turned on and off. By using the serial monitor in the Arduino IDE, you’ll be able to type a message on your computer, and the Arduino will translate it into tones in Morse code. To show how this works, we’ll use a simple buzzer to convert text into an audible Morse code signal. By encoding letters of the alphabet into combinations of dots and dashes, messages can be conveyed with only a single electric or audible signal. Morse code was developed in the 19th century to send messages over long distances using very simple sequences of long and short pulses, commonly referred to as dots and dashes. In this guide, we’ll show you how to create a device that can turn the text you type into audible Morse code messages automatically. However, the nature of Morse code makes it excellent for writing and generating messages using the Arduino. View the decoded Morse code in the serial monitor.Morse code is a fun way to communicate if you’re into secret messages.
Bekijk de gedecodeerde Morse-code in de serial monitor. And connect a buzzer between Arduino pin 8 and GND. En sluit een buzzer aan tussen Arduino pen 8 en GND. Connect a tactile switch (or key) between pin 7 of the Arduino and GND.
