delay but not stopping the program
Jan 19th, 2007, 4:07pm  
How do you set something on (in my case a pin on an arduino board) for an amount of time (24ms) and then off for an amount of time(38ms) but not with using delay(), because while this loop is going to make a square wave On/Off another pin on the arduino board needs to give another timed pulse for example 22ms On an 40 ms Off

thx

you can use java's Timer class:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Timer.html
or the swing timer class:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/Timer.html
for the latter you'd need to add "import javax.swing.Timer" to the beginning of your sketch.
a longer tutorial can be seen here:
http://java.sun.com/products/jfc/tsc/articles/timer/
avoid the mentions of "swing" in particular, but it should clarify how things work with the swing timer.
