Practise and decode morse code with Arduino! Note, this project is still underway, join in on the development by making it and submitting changes to github! Listen to secret coded messages on the ...

Once you have the audio it is fed into a pair of XR-2211 Tone decoders. This provides just three interface pins for the Arduino to watch.

In this project we will develop a tone generator using Arduino Uno. We will have buttons interfaced with the UNO and each one of them generates different intensity of tone. The frequency of tone ...

Schematic and Hardware: The schematic of this Arduino Tone Generator Project project is shown in the figure below: The connection is pretty simple we have a Piezo speaker which is connected to pin 8 ...

While many of us have banished land line telephones from our houses, there are still quite a few people who utilize POTS lines today. These analog phone systems use Dual Tone Multi Frequency (DTMF)… ...

The project involves coding the Arduino while sequencing 8 tone slots and the frequency of each slot would be controlled by a frequency knob. The controls on this console include four potentiometers ...

This library provides full access to the functions of the WT2003S MP3 decoder through a serial connection and a "busy" pin. This library is very simple to use with either a hardware or software serial ...
