|
// for second file, etc. Play may also be initiated by writing an analogue
|

// value to the first pin, e.g. SERVO(10000,23,0) will play the 23rd mp3 file.
|
|
// SERVO(10000,23,30) will do the same thing, as well as setting the volume to

// 30 (maximum value).
|
|
// Play is stopped by RESET(10000) (or any other allocated VPIN).
|
|
// Volume may also be set by writing an analogue value to the second pin for the player,
|
|
// e.g. SERVO(10001,30,0) sets volume to maximum (30).
|
|
// The EX-RAIL script may check for completion of play by calling WAITFOR(pin), which will only proceed to the
|
|
// following line when the player is no longer busy.
|
|
// E.g.
|
|
// SEQUENCE(1)
|
|
// AT(164) // Wait for sensor attached to pin 164 to activate
|
|
// SET(10003) // Play fourth MP3 file
|
|
// LCD(4, "Playing") // Display message on LCD/OLED
|
|
// WAITFOR(10003) // Wait for playing to finish
|
|
// LCD(4, " ") // Clear LCD/OLED line
|
|
// FOLLOW(1) // Go back to start
|
