writing a code for 2 relays with 2 buttons and actuators
-
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..

@SandeshHs94 The MySensors library RelayActuator example shows how to handle 2 (or more) child node messages. There is no need to change this incommingMessage function when adding a button. Adding button requires read functionality in the loop()
This sketch should work with 2 buttons (attached to pin 6 and 7)

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

@SandeshHs94 The sketch exactly is that: a combination of the relayActuatorWithButton and
relayActuator.. examplesThis line does several things
digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);message.getBool() --> gets the "payload of the message" in this case 1=ON or 0=OFF
message.sensor --> gives the node id for which the message is meant for
RELAY_1 --> is the first pin definition (for this sketch 3)
RELAY_ON --> equals pin HIGH
RELAY_OFF --> equals pin LOWdigitalWrite(pin, value); --> sets an output pin in this case pin: message.sensor-1+RELAY_1 (so either pin 3 for node 1 or pin 4 for node 2 messages)
The ? is a short notation for an if statement so when the message.getBool() = 1 the pin is set to HIGH and when 0 the pin is set to LOWI'm not sure why you want no "for-loop", but the sketch would look like this example

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...
