Connect the SDA pin to the following analog pins on the first Arduino: A4 for the transmitter display. A4 for the receiver display. Connect the SCL pin to the following analog pins on the first ...

This project is a simple Serial Transmitter - receiver unit of morse signals transmitted as light pulses of fixed on and off durations. Connect the Transmitter to an input device, here the laptop ...

Initially we build a transmitter and receiver to communicate between Arduinos using Morse code sent by pulses of light waves. Next, we consider digital music, which we create by switching a voltage on ...

For the project he revised his old code, adding in a Morse look-up table so that the Arduino Mega 2560 can convert plain text into dots and dashes. It uses the tone library to output signals to ...

LaunchPad dev boards from Texas Instruments are cheap and easy to program, making them a great Arduino alternative if you can do without some of the bells and whistles. [ech0s] put his to good use … ...

A transmitter controller is (you guessed it) what controls the transmitters: Turning them off-and-on at the right times and having them send specific Morse code signal patterns. Arducon does all ...

The Morse key is a switch that connects and disconnects the 12V power to the rest of the circuit. It has a wooden knob on the top, which makes tapping out the Morse code easier.
