Working with SAM-3

Here's the routine to pass cmd at repeatedly to the SAM-3.



/*
 SAM motor player

 This sketch shows how to use the serial transmit pin (pin 1) to send SAM motor data.

char inByte = 0;         // incoming serial byte
char firstSensor = 0;    // first analog sensor
char secondSensor = 0;   // second analog sensor
char i =0;

  Serial.begin(115200);

}

void CmdOn(int data1, int data2) {
  Serial.write(0xFF);
  Serial.write(data1);
