I'm so sorry for such late reply... the reason i wanted no for loop was to see how the code for that would turn out...

I have a project in mind with requires maybe 2 switches and if one is turned on then regardless of the message coming from controller for the second light it should stay off...

amazing.. thanks a lot but what about if i have to combine relayActuatorWithButton and
relayActuator..
do you have any code for that?
and please explain what this line means and how it works..
digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);

and how i can make the combination work without a for loop

Thank you

i want to add two buttons and two relays, i dont understand on how to combine them.

I am having trouble with the incomingMessage function. The relay with Actuator example works fine but it does not have a button, what if i want a button or if i have relays on non-consecutive pins.

i tried writing two functions for incoming message and it was just a foolish idea and i'm stuck.

how do i get it to work.. please help..

Guys,
I am completely new to mysensors and to date i feel this is the best approach, i dont understand a few basics, please answer to these questions.(I want to use serial gateway)

1)If i use arduino uno instead of mini/nano as given in sketch, should i be changing anything in the code given.

2)If i ad any new sensor should i add anything in gateway code for it to receive data or send data.

3)Can i add a sensor to gateway module itself.

4)If i choose to write a new code which is not in examples, how can i do it. is there any programming guide.

i would really appreciate if anyone can provide a complete guide link. I am sorry for such questions, i really need these answers.
Thank you
