Hello!
Im kinda noobish around here, but Im trying and I can say I have learned a lot in a few weeks or so.
I came on a problem.
I have a desire to connect two seperate arduino boards in order to send 2 integres from one to another.
So from board number 1 I would like to send two integres each ranging from -15000 to 15000 to board number 2.
So any suggestions how to do it?
I looked up at many ways such as I2C or stuff like that but i never managed to get a simple code out of it just sending two integres.
The other problem is the speed. How fast I need it to send. I need it to change at speed of 0.1 seconds on the board number 2. So every 0.1 seconds new value of int.
It's that even possible?
Thanx
I've used the below code to communicate from one arduino to another arduino.
//zoomkat 3-5-12 simple delimited ',' string tx/rx
//from serial port input (via serial monitor)
//and print result out serial port
//Connect the sending arduino rx pin to the receiving arduino rx pin.
//Connect the arduino grounds together.
//What is sent to the tx arduino is received on the rx arduino.
//Open serial monitor on both arduinos to test
String readString;
void setup() {
Serial.begin(9600);
Serial.println("serial delimit test 1.0"); // so I can keep track of what is loaded
}
void loop() {
//expect a string like wer,qwe rty,123 456,hyre kjhg,
//or like hello world,who are you?,bye!,
if (Serial.available()) {
char c = Serial.read(); //gets one byte from serial buffer
if (c == ',') {
if (readString.length() >0) {
Serial.print(readString); //prints string to serial port out
Serial.println(','); //prints delimiting ","
//do stuff with the captured readString
readString=""; //clears variable for new input
}
}
else {
readString += c; //makes the string readString
}
}
}
