Break line Serial Monitor PLEASE HELP PLEASE

Projects Programming
1

I made an app with mit inventor , it has a slider. the values are like
656361595755 when moving from 65 to 55 , so I want the serial monitor to break its line after every 2 digits. how do I do that ?? Please help :frowning:

edit : in the Code :

void loop() {
while(Serial.available()) {
delay(25);
char c=Serial.read();
if(c=='#')
{break; }
voice += c;
}

2

Print some spaces?
Use println?

Please post your Arduino program.

Here it is

void loop() {
while(Serial.available()) {
delay(25);
char c=Serial.read();
if(c=='#')
{break; }
voice += c;
}

I am a begginer and I don't know the meaning of these things..

Now is the best time to start learning.

And that can't be your complete program because it does not print anything to the Serial Monitor. In your Original Post you said "so I want the serial monitor to break its line after every 2 digits". Also, the code you posted in Reply #3 won't compile. Post the complete program in your next Reply.

Have a look at the examples in Serial Input Basics - simple reliable ways to receive data. The second example uses a linefeed character to identify the end of a message. I suspect your system is using the # character for that, and you could easily modify my example to use the # character.

Program :

void setup() {
Serial.begin(38400);

}

void loop() {
while(Serial.available()) {
delay(25);
char c=Serial.read();
if(c=='#')
{break; }
voice += c;
}
}

Actually I want that slider values so that I can Dim my LED's with bluetooth .

I think it would so is each pair separated by the '#' character or are you getting an non-delimited stream?

getting the delimiter for each pair of characters may be easier, IMHO.

Program :

Oh No it's not ...

Because when I tried to compile it I got this error (as I expected)

ArduinoTemp.ino: In function 'void loop()':
ArduinoTemp.ino:13:5: error: 'voice' was not declared in this scope
Error compiling.

If you really want help stop messing about.

Sorry for that, I accidentally didn't copy the first line of the code...

And really thanks for helping, I Learnt it now...

Thanks for the update.
