Hi Daniel
I tried this
byte relay_address=1;
void setup(){
Serial.begin(9600);
}
void loop(){
Serial.print(relay_address=1, BYTE); // send relay module address
Serial.print(100, BYTE); // All relays on
delay (1000);
Serial.print(relay_address=1, BYTE); // send relay module address
Serial.print(101, BYTE); // Turn relay 1 on
delay (1000);
//etc
Serial.print(relay_address=1, BYTE); // send relay module address
Serial.print(110, BYTE); //All relays off
delay (1000);
Serial.print(relay_address=1, BYTE); // send relay module address
Serial.print(111, BYTE); //Turn relay 1 off
delay (1000);
//etc
}
with the relay-address=1; no luck the tx lamp lights on the Arduino but no response from the board
also tried print n but sketch would not compile.
