1.6 - Norsk Data projects

The project

• This project requires no additional hardware parts, but only the Arduino board itself.
• The idea for this project comes when I removed a buzzer from a Tandberg keyboard, this might be used for something fun.
• However the project became more of an exercise in creating a working Arduino Morse library.
• This project is using my Morse library.

Hardware

• Arduino Uno
• Buzzer
• LED
• Resistor 240 Ω

• Use the Arduino board alone using the built in LED.
  or
• Connect an external LED or buzzer, as you please.

Software

• With this small program for the Arduino board, we can now send or print Morse code.
• This program can be downloaded and uploaded to the an Arduino board using Xloader.
• After downloading you can connect to the Arduino board using f.ex HyperTerminal.
• The program is using my own Arduino Morse library, version A00.
• The Arduino program COM001 has the following commands:
  • a - Send the Morse code for the entire defined Morse alphabet. You can cancel this at any time by hitting any key.
  • dn - Change the duration of a Morse dot, n is number of ms. All other durations are derived from this dot duration.
  • fn - Change the tone frequency used if a buzzer is connected, n is frequency in Hz.
  • h - Display the help screen.
  • mx - Send the given text (x) as Morse code out on the defined output pin.
  • pn - Change the output pin to be used, default is the built in LED, typical on pin 13.
  • R - Reset the Arduino board (warmstart).
  • s - Display the current program configuration/status.
  • wx - Write the given text (x) as a string of dots and dashes.

FAQ

• Do you have buzzers or LEDs that I can buy?
• Nope.

• Can I buy an Arduino Uno and/or Arduino prototype board from you?
• Yes, but IT IS much cheaper to find and buy it on the internet.

• Can you build or help me build this project?
• No, there is nothing to build.

• Can I have the Arduino source sketch so I can modify it myself.
• No, you can NOT. You have to write your own sketch.
