Hi. After tinkering with some code I finally managed to make this! ;D Here is the code.
// Ipod mood lamp
//By: Ryan Gosiaco
// Red led is MotorA=pin 9
// Green led is MotorB=pin 10
// Blue led is MotorC=pin 11
// I tweaked the code... so have fun!
#define PwmPinMotorA 9
#define PwmPinMotorB 10
#define PwmPinMotorC 11
#define DirectionPinMotorA 12
#define DirectionPinMotorB 13
#define DirectionPinMotorC 8
#define SerialSpeed 9600
#define BufferLength 16
#define LineEnd '#'
char inputBuffer[BufferLength];
void setup()
{
// motor pins must be outputs
pinMode(PwmPinMotorA, OUTPUT);
pinMode(PwmPinMotorB, OUTPUT);
pinMode(PwmPinMotorC, OUTPUT);
pinMode(DirectionPinMotorA, OUTPUT);
pinMode(DirectionPinMotorB, OUTPUT);
pinMode(DirectionPinMotorC, OUTPUT);
Serial.begin(SerialSpeed);
}
// process a command string
void HandleCommand(char* input, int length)
{
Serial.println(input);
if (length < 2) { // not a valid command
return;
}
int value = 0;
// calculate number following command
if (length > 2) {
value = atoi(&input[2]);
}
int* command = (int*)input;
// check commands
// note that the two bytes are swapped, ie 'RA' means command AR
switch(*command) {
case 'FA':
// motor A forwards
analogWrite(PwmPinMotorA, value);
digitalWrite(DirectionPinMotorA, HIGH);
break;
case 'RA':
// motor A reverse
analogWrite(PwmPinMotorA, value);
digitalWrite(DirectionPinMotorA, LOW);
break;
case 'FB':
// motor B forwards
analogWrite(PwmPinMotorB, value);
digitalWrite(DirectionPinMotorB, LOW);
break;
case 'RB':
// motor B reverse
analogWrite(PwmPinMotorB, value);
digitalWrite(DirectionPinMotorB, HIGH);
break;
case 'FC':
// motor C forwards
analogWrite(PwmPinMotorC, value);
digitalWrite(DirectionPinMotorC, LOW);
break;
case 'RC':
// motor C reverse
analogWrite(PwmPinMotorC, value);
digitalWrite(DirectionPinMotorC, HIGH);
break;
default:
break;
}
}
void loop()
{
// get a command string form the serial port
int inputLength = 0;
do {
while (!Serial.available()); // wait for input
inputBuffer[inputLength] = Serial.read(); // read it in
} while (inputBuffer[inputLength] != LineEnd && ++inputLength < BufferLength);
inputBuffer[inputLength] = 0; // add null terminator
HandleCommand(inputBuffer, inputLength);
}
Link to come!

BTW I posted this in interfacing hardware already because I didn’t know. :-/
