Play background sounds while running a light animation
Here are a few typical ways this is used.
Villages, factories, and buildings create noise of one sort or another. And then open areas, playgrounds, and roads do the same. A Christmas village display would have carols playing in the background.
All could be accompanied by some form of light display.
This application is applied on two levels. On the first the background starts as soon as the scene is turned on. On the second the sounds may start and stop on some specific call.
The first is easy. Power is applied to the payer simultaneously with It being applied to the scene. That requires only an auto-start player described above. The same switch that starts the player applies power to the scene which power may turn on lights.
The second requires an external stimulus. In its simplest form, that stimulus could be from a switch. But most often this comes from a separately programmed Arduino.
For example, sounds could start after all building lights are on and stop just before the lights start to turn off.
- Animate up to 12 LEDs.
- No wiring required. Just insert the parts into the holes in the circuit board and make simple solder joints.
- A player with a 32GB SD card makes it easy for you to play the sounds of your choice.
