What is Arduino DCC SoundShield?
Arduino DCC SoundShield is an accessory decoder designed to add realistic sound effects to model railways. It is composed of a microcontroller that communicates with Arduino, a 16 megabit memory to store audio files, a 3 watt amplifier to directly control the speaker, and a USB port to load audio files directly from a computer.
How Does it Work?
The Arduino DCC SoundShield works by decoding MP3 files and playing them through the 3 watt amplifier. When connected to a computer, a new CD drive appears with double cck. The user can then start the program for loading MP3 files on the module. Once the files have been selected, they can be uploaded to the module by pressing the Flash button.
What Sounds Can it Produce?
The Arduino DCC SoundShield can produce a variety of sound effects, including station announcements, locomotive whistles, level crossings, and generic background music. These sound effects can be used to coordinate with the other dynamic elements of the model railway.
Where Can I Find Audio Files?
Audio files can be found in the GitHub repository for this project. There are also some demo tracks that can be used to verify the functioning of the decoder. Additionally, audio files can be purchased from online shops that specialize in model railway sound effects.
Are There Tutorials Available?
Yes, there are tutorials available on YouTube for programming non-programmed modules. These tutorials can help users get the most out of their Arduino DCC SoundShield.
The Arduino DCC SoundShield
The Arduino DCC SoundShield is a device designed to enable users to add sound and other effects to their model railway layouts. It is based on an Arduino microcontroller and is compatible with a variety of DCC decoders. The device is capable of playing up to 30 audio tracks and can be programmed to respond to specific DCC commands.
Getting Started
The first step in using the Arduino DCC SoundShield is to build the shield. This involves connecting the DCC signal and speaker to the two terminal blocks on the PCB. Once the shield is built, the user can then program the Arduino by inserting the sound shield and powering up the Arduino.
Programming the Arduino
Before programming the Arduino, it is important to perform a factory reset to initialize the values of all the CVs. This is done by holding down the program button and pressing the Arduino reset button. When the reset is complete, the LED on the shield will blink five times to indicate that the reset has taken place.
Configuring Audio Tracks
The Arduino DCC SoundShield is capable of playing up to 30 audio tracks. The audio tracks are read in alphabetical order, which is why it is recommended to use simple names such as 001.3 or 002.3. Each audio track corresponds to an address and two CVs. The first CV is used to configure the playback mode, single value, zero or loop value. The second CV is used to configure the playback volume from 0 to 30. The first track corresponds to the address of the decoder default: F, NCV, 101 and 102. The second track corresponds to other NCV increased by one, that is other 5 NCV, 103 and 104. This pattern can be used to identify the values of the next tracks.
Arduino DCC SoundShield
The Arduino DCC SoundShield is a powerful and versatile decoder that is capable of producing realistic sound effects for model trains. It is equipped with a microcontroller, an amplifier, and a speaker, and is capable of playing up to 20 different tracks. It can be programmed to play different tracks in response to commands from a DCC command station, allowing for realistic sound effects to be produced.
Factory Reset
The Arduino DCC SoundShield can be reset to its factory settings by pressing the program button. This will reset all trucks to single play mode with a default volume of 20. This means that each time the decoder receives a command, it will play the corresponding track.
Modifying CV 103
The value of CV 103 can be modified to set track two in loop mode. This means that when the decoder receives a command for straight position, it will begin to play track two in a loop. The loop can be stopped by sending a command for diverging position to the same address, or by sending a command to play another track.
Programming the Decoder
The decoder can be programmed by pressing the program button. The LED will light up, and the decoder will change address based on the address of the first command it receives. For example, if a command is sent to address 8 using a DCC command station, the decoder will take on address 8. The LED will turn off when programming is successful.
Using Decoder Pro
If you are using Decoder Pro, you can download a specific definition for the SoundShield decoder from GitHub and save it in the decoders folder of your JMRI Music installation. You can then select Actions > Recreate Decoder Index and add the decoder. You can then use the Read Type from Decoder function to identify the decoder as a Sound decoder.
