perhaps a little help with servo control??

hello everyone,

here's goal, pretty simple - little prototype larger project....

i need able control 9 servo's 1 board (decimilia) independently.  i'm bit new @ writing code however, approach write separate functions each servo, , call functions in main loop in whatever order necessary achieve desired effect.  

i have code runs of them @ once, (just test see if power supply sufficient) -
how modify or re-write code independent control , choreographed sequence of actuations?

code: [select]



#define servoa 13
#define servob 12
#define servoc 11
#define servod 10
#define servoe 9
#define servof 8
#define servog 7
#define servoh 6
#define servoi 5


#define min_pulse 600
#define max_pulse 2400
#define delta 1800


int lastpulse = 0;
int refreshtime = 20;

long randnumber;

void setup()
{
 int i;

thanks in advance !!

q. supply adequate power 9 servo's ?
