Hi everyone!
I bought my first arduino a month ago, and have been having fun with it. However, last night I was trying to send signals from a TX433 to a RX433 on 2 different unos. First thing to note though is that the TX says it's 433.92MHZ while the RX just says 433 MHZ. I've been trying different configurations and different codes to get them to work but no avail (meaning the serial monitor doesn't show anything at all). Do you think it's because their frequencies are different? (I emailed the store I bought it from , and they insisted that they were compatible, despite that they were from 2 different suppliers). Otherwise, what am I missing? Here are some pics of how I've set them up, and I also posted the code I am trying right now (amongst the other ones I've tried).
Thanks so much guys!
TRANSMITTER:
/*
* Simple Transmitter Code
* This code simply counts up to 255
* over and over
* (TX out of Arduino is Digital Pin 1)
*/
byte counter;
void setup(){
//2400 baud for the 434 model
Serial.begin(1200);
counter = 0;
}
void loop(){
//send out to transmitter
Serial.print(counter);
counter++;
delay(10);
}
RECEIVER:
/*
* Simple Receiver Code
* (TX out of Arduino is Digital Pin 1)
* (RX into Arduino is Digital Pin 0)
*/
int incomingByte = 0;
void setup(){
//2400 baud for the 434 model
Serial.begin(1200);
}
void loop(){
// read in values, debug to computer
if (Serial.available() > 0) {
incomingByte = Serial.read();
Serial.println(incomingByte, DEC);
}
incomingByte = 0;
}
