I'm working on a project where I transmit data from Max to Arduino to change the RGB values of a multicolor LED.

The multicolor led I'm using reads RGB values in bytes 0-255, but if the only data are numbers in that same byte range, its tricky for me (not an expert) to parse it to the R, G, and B values individually, since the possible range of values I can input is the same as the data needed to change the RGB values. I can't send a different outlier value from Max to Arduino for an Serial.read if statement to recognize and parse the previous value to the R, G, or B.

object as 3 ints ("0 0 255" for blue) and I'm attempting to in Arduino use an array to store three numbers, parse them to the R G and B values, then reset for the next three values coming in, but I'm worried that won't work if it's getting a lot of values in quickly (mousing on a 

Is there any way to send different data that I can use to parse to R G and B from the 

 object, or is it only single integers 0-255.

I'm formatting the message to the serial object as 3 ints ("0 0 255" for blue) and I'm attempting to in Arduino use an array to store three numbers, parse them to the R G and B values, then reset for the next three values coming in, but I'm worried that won't work if it's getting a lot of values in quickly (mousing on a swatch object for example).

Is there any way to send different data that I can use to parse to R G and B from the serial object, or is it only single integers 0-255.

LED RGB Max to arduino was really posted many times on the forum.

in few words, you send 3 ints and line feed at the end.

In arduino use parseInt to capture 3 ints and assign them to your values.

void loop() {if(Serial.available() > 0) {

here you write what you want with that 3 values

You can increase serial baud rate if you feel it needs to be faster.

void setup() {Serial.begin(57600);}

void loop() {if(Serial.available() > 0) {
int R = Serial.parseInt();
int G = Serial.parseInt();
int B = Serial.parseInt();
if (Serial.read() == '\n') { here you write what you want with that 3 values }
}}

serial object: transmit byte (0-255) data only?
