Here is some simple code for the Mini Maestro 12. It moves 2 servos and blinks the built in LED.

void setup()// run once, when the sketch starts { Serial.begin(9600);// set up Serial library at 9600 bps //Serial.print(0xAA,BYTE); pinMode(13, OUTPUT); }


void loop()// run over and over again

{

  put(0,3000); //move servo 0

  put(1,3000);  //move servo 1

  digitalWrite(13, HIGH); //chane led state so you know its running

  delay(1000);

  put(0,4000);

  put(1,4000);

  digitalWrite(13, LOW);

  delay(1000);

}
void put(unsigned char servo, unsigned int angle){

  //servo is the servo number (typically 0-7)

  //angle is the absolute position from 500 to 5500
  //Send a Pololu Protocol command

  Serial.print(0xAA,BYTE); //start byte

  Serial.print(0x0C,BYTE); //device id

  Serial.print(0x04,BYTE); //command number

  Serial.print(servo,BYTE); //servo number

  //Convert the angle data into two 7-bit bytes

  Serial.print(((angle>>7)&0x3f),BYTE); //data1

  Serial.print((angle&0x7f),BYTE); //data2

}

great job, this is what i’ve been looking for..a clear explanation about the arduino and the pololu servo controller for my project..could you email me about some simple arduino code to drive 1 or 2 servo using this servo controller..
Thanks a lot

I didn’t test a lot them because I got many problems and I immediatly decided to buy better servos : )

Sorry

looks great!

could you comment more about the issues with the cheap servos ? thanks!
