random coding

[dze]

hi
got a newbie programming question. I'm quite familiar with Maxmsp and all i would like to achieve with programming arduino is this.

I have say 5 different 'presets' or say '5 different sequences' of led blinking. Everything a trigger is send from a sensor, it does a random of 0 - 4 and chooses just 1 number, say sequence 2. After Sequence 2 is over, and when another trigger is receive, it does the random function again.

how can i achieve this with arduino programming? what kind of statements would I use?

best

The "random()" function is the one to use: http://arduino.cc/en/Reference/Random
You will probably also want to add a call to randomSeed() in your setup: http://arduino.cc/en/Reference/RandomSeed

This statement:

Code: Select all

int sequence = random(5);


will give you a number between 0 and 4.
